A griddle cover is the cheapest insurance a flat-top owner can buy. The best griddle covers for outdoor storage in 2026 come down to three picks: the Blackstone 36 Inch Griddle Cover for a factory-fit match on a 36 inch model, the iCOVER 36 Inch Griddle Cover when you want one cover to fit several brands, and the Blackstone 5483 28 Inch Griddle Cover if your griddle has a hood and you want the OEM warranty behind it.
I compared 12 covers across 600D polyester, 1000D Oxford, PVC and PU coated fabric, and a rigid aluminum lid, weighing fit, seam construction, wind securement, and what actually happens after a few seasons of sun. The differences are not subtle. A cover with side buckles and a bottom drawstring behaves completely differently in a storm than one that relies on a loose hem, and that is the difference most owners discover the hard way.
If you are still choosing the appliance itself, our griddle and grill combo roundup covers the units people pair with these covers. The short version here: a griddle is bare rolled steel with a powder coat that fails first under UV and moisture, and a cover removes the need to haul a heavy appliance indoors after every cook.
One more note before the picks. The second most repeated owner complaint, after covers blowing away, is trapped condensation. A tight, unvented cover over a damp griddle will keep moisture against the steel, which is worse than no cover at all. We deal with that step properly in the maintenance section below.

Everything below is grouped by what the cover is built for rather than by brand, because a tabletop 17 inch model and a 36 inch four-burner have nothing in common except the word griddle.
1. Blackstone 36 Inch Griddle Cover – Best Overall for 36 Inch Griddles
Blackstone® 36 inch Griddle Cover
600D water-resistant polyester
Poly-resin buckles clip under the base
Form-fitted to 36 inch model with shelf
Pros
- Form-fitted OEM design
- Double-layered canvas with reinforced stitching
- Buckles that clip under the griddle base
- Water beads on the 600D polyester
- Hose-off cleaning
Cons
- Only fits the 36 inch model with shelf attached
- Fabric creases at first until it relaxes
This is the cover the griddle maker builds for its own 36 inch station, and that factory fit is the entire value proposition. It is designed for the 36 inch griddle with shelf attached and the Tailgater, and it clips to the base with poly-resin buckles rather than wrapping straps around the legs.
With 29k+ reviews at 4.8 stars, this is the most proven cover in the group by a wide margin, and the review pattern is consistent. Owners describe thick canvas that feels closer to gear fabric than to a patio tarp, water beading on the surface, and buckles that stayed put through wind.
The construction is double-layered with reinforced stitching, which is where most of the cheap covers in this category fail. Seam failure is the number one reason a two-season cover stops keeping water out, and the difference is visible when you look at the stitching on a 600D cover versus a 420D one.
Wipe-down or hose-off cleaning handles bird droppings, pollen, and dust without any special treatment. A neutral black finish also keeps it looking intentional next to a grill rather than like a tarp thrown over furniture.
The one thing that catches people out is fit. This is a form-fitted cover for one specific configuration, so it will not stretch across a 36 inch Pro Series, a cabinet model, or any other brand. Measure before ordering, because there is no universal give in this design.
Why the factory fit is worth paying for
The buckles clip under the griddle base, which means wind cannot get under the hem and lift it. That single detail resolves the complaint we see repeated most often in griddle owner forums, where fabric covers with no base securement end up in the neighbor’s yard.
When to buy something else instead
Buy a universal cover instead if you own a 36 inch Pro Series, a cabinet-style griddle, or a second-brand flat top. New fabric also creases sharply out of the package and needs a day or two of sun to relax, which annoys people who expect a crisp fit immediately.
2. iCOVER 36 Inch Griddle Cover – Best Universal Fit Across Brands
iCOVER 36 inch Griddle Cover for Blackstone, Waterproof Flat Top Grill Cover, Fits Camp Chef, Blackstone 1528 & 4 Burner Griddle
65 by 22.5 by 26 inch
Waterproof oxford with PVC coating
Side buckle straps plus bottom drawstring
Pros
- Widest compatibility in the roundup
- Side buckles plus bottom drawstring
- Double-reinforced corners
- Hose-down cleaning
Cons
- Does not fit the 36 inch Pro Series
- Lightest fabric of the heavy group
- 4.4 stars carries the largest low-rating share
This is the pick when your griddle is not a standard 36 inch four-burner, or when you want one cover that handles more than one appliance. It is listed at 65 by 22.5 by 26 inch and fits models from Blackstone, Camp Chef, and Weber.
At 51k+ reviews it is the largest review pool we found, and it ranks first in Grill Covers within Patio, Lawn & Garden. The rating sits at 4.4, which is the honest read on a cover this broadly compatible: most people love the fit, a minority hit fit or fabric thickness problems.
The securement is the strongest in the roundup, with buckle straps on both sides and a drawstring along the bottom hem. That combination closes the gap that wind exploits, and buyers who measure before ordering report high satisfaction with the closure.
The fabric is PVC-coated oxford polyester with double-reinforced corners, and the outer coating is UV resistant. A hose-down clears it, and the finish resists staining well enough that you do not think about it between cooks.
Buyers who did not measure are the source of the low ratings. It is also lighter than the 1000D and canvas competitors, so in exposed high-wind locations the material itself flexes more under gusts even though the closure holds.
Where the fit list earns its keep
Listed compatibility covers several Blackstone four-burner numbers, Camp Chef, and a Weber model, which makes it the pragmatic choice for households with a griddle and a flat top of a different brand. The 65 inch length also gives room over a no-hood body.
When the lower rating should steer you away
Skip it if your griddle is a 36 inch Pro Series, which is excluded, or if your setup sits in a coastal or open hillside spot where fabric weight matters as much as closure. The material is the lighter option in this group, and that shows in a gust.
3. Flybold 36 Inch Hard Cover – Best Hard Shell Storage Upgrade
Flybold 36 Inch Blackstone Griddle Hard Cover – Aluminum Flat Top Grill Lid with Suitcase Handle – Lightweight, Weatherproof, Diamond Cut BBQ Replacement Cover for Blackstone & Member’s Mark Griddles
Diamond-cut aluminum shell
Weighs 7.3 pounds
Suitcase handle and dual hangers
Pros
- Rigid shell blocks sun and debris
- Aluminum resists rust and fading
- About half the weight of a 13 pound hard lid
- Suitcase handle for quick removal
- Dual hangers double as a wind guard
Cons
- Fixed size limits it to specific 36 inch models
- Heavier than any fabric cover here
A rigid aluminum lid solves a different problem than a fabric cover. It does not depend on buckles, drawstrings, or stitching, so it cannot be lifted by wind and it never traps condensation under a hem. It just sits there and takes weather.
Owners in griddle forums consistently recommend a hard lid for year-round outdoor storage, and the reasoning matches the physics. Fabric covers fail at seams and fade; an aluminum shell has no seams to fail and no fabric to bleach.
The weight is the headline detail. At 7.3 pounds this is roughly half of what a comparable stock hard lid weighs, which is the difference between lifting the lid with two fingers and hauling it off the griddle. Owners also like that the powder-coated black finish matches the appliance.
The dual hangers let the lid rest on the back rail of the griddle rather than on the ground, and they double as a wind guard when the griddle is in use. That is a small design touch that avoids leaning a flat sheet against a vertical surface in a storm.
Size is fixed, and that is the trade-off. It is built for the 36 inch Blackstone and Member’s Mark griddles, so a different brand or a Pro Series body will not work, and there is no adjustment to make it fit.
Who gains the most from a rigid lid
Owners in snow country and anyone leaving a griddle out through the whole off-season get the most from it. A shell has no fabric to stiffen in cold weather, no buckle to freeze, and no seam to admit meltwater over months of storage.
Where it does not fit the job
Choose fabric instead if you carry your griddle to a different location, or if you need one cover to flex across two different griddle bodies. A fixed-size aluminum lid cannot stretch, and storage in a tight garage corner is harder with a rigid slab than with a bag you can roll.
4. Unicook Cover for Blackstone 22 and 28 Inch Single Shelf Griddles – Top Rated Sealed-Seam Build
Unicook Griddle Cover for Blackstone 22″ 28″ Single Shelf Griddle
45 by 23 by 25 inch
Waterproof vinyl lining with sealed seams
Center support post sheds water
Pros
- Hot-melt seam sealing tape
- Vinyl lining for all-weather sealing
- Hook-and-loop straps secure in seconds
- Center post sheds standing water
- Handles for hanging and storage
Cons
- Not compatible with Pro Series and counter-height shelves
- Not machine washable
- Straps can degrade after seasons of UV
The sealing is what separates this one. Hot-melt seam sealing tape over a waterproof vinyl lining is a genuine weather seal rather than a stitched-only seam, and that is the construction detail that decides whether water reaches the steel after a season of rain.
At 4.8 stars across 7k+ reviews it is one of the two highest-rated covers we found, and reviewers point to thickness, holding up in heavy rain, staying put in wind, and the center support as the recurring positives.
That center support post is a small idea with a real effect. It lifts the fabric off the cooking surface and sheds standing water, so a heavy rain event does not leave a pool sitting on top of the cover pressing down on the griddle underneath.
Hook-and-loop side straps hug the griddle and secure in a couple of seconds, which matters when you are covering a hot-adjacent appliance in bad light. Handles on the cover make it easy to fit, remove, hang, and store folded.
Compatibility is the constraint to check. It fits 28 inch griddles including the Blackstone 28 and many Nexgrill models at 45 by 23 by 25 inch, but not the Pro Series or the counter-height shelf models.
Why sealed seams matter more than fabric weight
Water enters a cover through a stitched seam long before it finds a way through the fabric itself. A cover with sealing tape keeps the seam watertight even where the material is lighter, and that is why this one holds up in climates with frequent rain rather than occasional drizzle.
When to pick a different cover
Go elsewhere if you own a Pro Series or counter-height shelf unit, or if you want to machine wash the cover between seasons. Hook-and-loop straps also pick up grit over time and can degrade after a couple of seasons of strong sun, so check them annually.
5. NOELIFE Cover for Blackstone 22 and 17 Inch Griddles With Stand – Best for Tabletop Models
Griddle Cover for Blackstone 22″ 17″ Grill with Stand, Cover Only
Fits 17 and 22 inch griddles with stand
Sealed seam tape,600D high-density fabric
Double wind lock with straps and buckle
Pros
- Sealed seam tape over waterproof inner and outer layers
- Hook-and-loop plus adjustable bottom buckle
- 600D high-density fabric resists tearing
- UV-proof fabric limits fading
Cons
- Narrow fit window
- Listing dimensions show 1 by 1 by 1 inch
- Excludes several similar 17 and 22 inch configurations
Tabletop and portable griddles get ignored in most cover roundups, and that leaves a real gap. This one covers the 17 and 22 inch Blackstone griddles that come with a hood on a stand, which is the configuration most tabletop owners actually own.
At 4.6 stars across 4k+ reviews, the reviews concentrate on solid waterproofing and strong wind resistance for people inside the fit window. The construction is 600D high-density fabric with sealed seam tape and waterproof inner and outer layers.
The wind lock is doubled. Hook-and-loop side straps handle the top-down pull, and an adjustable bottom buckle straps tight underneath, which stops the lift that flattens a loose cover into a sail.
UV-proof fabric is the other piece owners mention, since a tabletop griddle on an open patio takes full sun whenever it is not cooking. Fading is the failure mode that ruins a light-colored cover fastest, and this one is rated to resist it.
The caveat is fit, and it is a meaningful one. The listing shows 1 by 1 by 1 inch dimensions, so you get no usable sizing information, and the brand excludes the 22 inch hood-and-cart model 2063, the Pro Series 22, the 17 inch tailgater, and Duo 17 inch combos.
Why tabletop griddles need their own cover
A tabletop griddle spends its life on a picnic table or a small stand, which means more direct sun and more water pooling than a full-size cart. A cover matched to that body keeps grease channels and burner knobs from clouding with pollen and sap.
What to verify before ordering
Confirm the exact model, because similar-looking 17 and 22 inch units do not share a cover shape. If your listing gives no real dimensions, treat that as a reason to measure the griddle including its stand, not as a reason to assume it fits.
6. NettyPro Cover for Blackstone 36 Inch Griddle – Most Versatile with Six Buckles and a Vent
NettyPro Griddle Cover for Blackstone 36 inch Griddle, Waterproof UV Resistant 4 Burner Flat Top Gas Grill Cover 36″ Cooking Station, Black
67 by 27 by 32 inch
PU-coated ripstop with covered seam tape
Two side straps plus four bottom buckles
Pros
- Six buckles for serious wind
- Solid plastic buckles hold up in rain and wind
- Covered front air vent reduces condensation
- Generous sizing fits most 4-burner models
- Color options beyond black
Cons
- Fades faster than the fadeproof claim suggests
- Fabric weakens after several seasons of sun
- No storage bag
This is the most aggressively secured fabric cover in the group, with two adjustable side straps and four bottom buckles. Reviewers in exposed hilltop locations report the cover never budged, and the buckle hardware is solid plastic rather than hook-and-loop, which is the difference that matters in wet weather.
The covered air vent at the front is the second feature worth knowing about. It exists specifically to prevent condensation under the cover, which is the failure that quietly causes rust on covers with no ventilation at all.
Material is high-density PU-coated ripstop with fully covered seam tape and double stitching, sized generously at 67 by 27 by 32 inch to fit griddles up to that size, including most 4-burner Blackstone and Weber models. The ripstop grid is what resists tearing once a corner catches on something sharp.
Color is a small but real differentiator. Black, brown, and beige are available, and brown or beige on a deck look deliberate where a black tarp reads as an afterthought.
Owners are honest about the weak point: long-term fade resistance. A five-year owner reported near-white fabric, and reviewers note the material weakens with years of sun and can tear on sharp corners when pulled on. Treat it as a cover that performs well and eventually needs replacing.
What six buckles actually buy you
Wind does not push a cover sideways so much as it slides underneath and levers the whole thing up. Four bottom buckles close the bottom edge along its full length, and solid plastic hardware does not absorb water and go slack the way hook-and-loop does.
Who should not expect it to last forever
If your griddle sits in full southern sun with no shade, plan on replacing this cover within a few seasons. The fadeproof claim does not match the five-year reports, and no storage bag is included for the winter months when it is off the griddle.
7. ULTCOVER 600D Cover for 28 Inch Griddles – Best for Two Side Shelves and a Hood
ULTCOVER 600D Outdoor Waterproof Griddle Cover, 28 inch
60 by 30 by 35 inch
600D polyester canvas with waterproof backing
Side air vents and draw cords to wheel legs
Pros
- Sized for 28 inch griddles with two side shelves
- Waterproof backing holds off rain hail and snow
- Structured side vents reduce billowing
- Plastic clips and draw cords anchor to wheel legs
Cons
- Must wait for full cooling before fitting
- Oversized on smaller single-shelf griddles
- Higher priced than lighter fabric covers
Most 28 inch covers are cut for a single-shelf body. This one is built for the larger configuration, with two side shelves and a flap top with a hood, sized at 60 by 30 by 35 inch for the XL version.
At 4.7 stars with 2k+ reviews and only a small one-star share, the reviews point to two things: the ventilation, and the leg-level anchoring. Those are the two details that separate a cover that stays put from one that flaps.
Material is 600D polyester canvas with a waterproof backing, which is a heavier weave than most covers in the budget and mid tiers. It handles rain, hail, snow, leaves, and bird droppings, and the full-coverage design keeps the griddle looking new between cookouts.
Securement runs through the structure rather than around it. Plastic clips and heavy-duty elastic draw cords anchor to the wheel legs, and structured air vents at two sides cut billowing, which reduces the load the fabric takes in a gust.
Fit is the thing to verify, because a cover this generous will not hug a smaller single-shelf griddle. You also need to let the griddle cool fully before pulling the cover on, which is good advice regardless of brand.
Why vents and leg cords work together
Billowing is what tears covers. A flap that catches wind at the edge generates force across the whole panel, and structured vents bleed that pressure. Anchoring to the wheel legs adds a lower tie point, which stops the bottom edge from peeling up as the first step of a lift.
When a smaller cover is the smarter buy
Choose a tighter single-shelf cover if your 28 inch griddle does not have both side shelves and a hood. Paying more for a panel that is too large is paying for fabric that flaps, and oversized covers snag on sharp corners when you pull them into place.
8. KINGLY 1000D Heavy Duty Cover for Blackstone 36 Inch – Best Heavy-Duty Fabric Pick
1000D Heavy Duty Griddle Cover for Blackstone 36″ Griddle,100% Waterproof
67 by 23 by 26 inch
1000D Oxford fabric
UPF 50 plus UV blocking and two air vents
Pros
- Heaviest fabric class here at 1000D
- Sealed double-stitching over waterproof layers
- UPF 50 plus blocks 99.99 percent of UV
- Side straps plus extra bottom straps
- Handles and two side air vents
Cons
- Excludes Pro Series and several specialty 36 inch models
- Hook-and-loop straps wear faster than buckles
Fabric weight is the number people look at, and this is the heaviest in the roundup. The 1000D Oxford weave is rated at roughly twice the tear and abrasion resistance of 420D or 600D fabric, and buyers consistently call out the thickness relative to what they paid.
At 4.7 stars across 2k+ reviews, the other thing reviewers mention is the combination of small features: two side air vents, portable handles, and straps both at the side and the bottom. None of those is exotic on its own.
Waterproof outer and inner layers with sealed double-stitching seam tape keep the griddle dry, and UPF 50 plus fabric blocks 99.99 percent of UV rays. That UV figure is the one that slows the fading and cracking that turns a black cover grey after two summers.
Lengthened and widened adjustable side straps work with extra bottom straps, giving a double wind security setup. Side handles make on and off fast and give you somewhere to hang it when it is folded away.
Compatibility is the trade-off. It fits Blackstone 36, Camp Chef 600, Royal Gourmet, and most 4-burner griddles at 67 by 23 by 26 inch, but excludes the 36 inch Pro Series, rangetop, air fryer, cabinet, hood, and Culinary models.
When the heavier fabric earns its cost
Thick weave matters where covers are handled roughly, dragged across concrete, or stored in a damp shed between seasons. It also stays rigid in cold weather, so it does not need to relax before it goes on, which is a real advantage in winter conditions.
Where hook-and-loop costs you
The closure here is straps and hook-and-loop, and hook-and-loop is the first thing to fail in this category. Grit in the hook, then UV embrittlement, and the strap loses grip in the third season while a plastic buckle simply keeps clipping.
9. Blackstone 5483 28 Inch Griddle Cover – Best Owner-Matched 28 Inch Cover
Blackstone® 5483 28″ Griddle Cover, Black
Water-resistant 600D polyester
PVC coating and fade resistance
Semi-elastic clinch straps and clips
Pros
- OEM 600D polyester with a coated finish
- Clinch straps and clips held through storms
- Generous fit covers tank and front shelf
- Black dye has not faded
- Hose-off cleaning and quick on and off
Cons
- Roomier than some setups expect
- Fits 28 inch Blackstone griddles with a hood only
- New creases take about a day of sun
If you own a 28 inch Blackstone with a hood, this is the factory cover, and the rating distribution backs it up. It runs 89 percent five-star and 8 percent four-star, with no one or two-star reviews at all, which is the cleanest spread in the group.
Owners upgrading from an off-brand cover call out the same three differences every time: fabric thickness, fit, and wind security. The 600D polyester with a water-resistant PVC coating feels closer to backpack fabric than to the thin covers people buy first.
Securement is semi-elastic clinch straps and clips, and owners report them holding through thunderstorms and hail. The fit is generous enough that the propane tank and front shelf sit under one roof rather than peeking out, which is the detail that causes rust spots.
Maintenance is unremarkable in a good way. It hose-offs, folds compactly, and rolls on and off in seconds. The black dye has not faded in the reviews, and the fabric protects against rain, snow, heat, dust, and insects year-round.
It carries a one-year limited warranty, which is the accountability signal most third-party covers cannot offer. The caveat is sizing again: it fits 28 inch Blackstone griddles with a hood, and it runs longer than some people expect, so you may need to move the griddle while it is covered.
What a factory cover does with your tank
The generous cut is the functional point. Most fitted covers stop at the cook box, which leaves the propane tank, the front shelf, and the grease tube exposed to standing water. Covering all three removes the two spots where surface rust starts first.
When to expect a snugger fit
If your 28 inch has no hood, or if your setup is tight against a wall or railing, the roomy cut works against you. Owners also note that new creases need roughly a day of sun before the fabric relaxes into its shape.
10. Onlyfire 36 Inch Cover for Blackstone – Best for RV and Camping Setups
Onlyfire Griddle Cover for Blackstone 36″ Griddle, 600D Heavy Duty
66.5 by 22.5 by 26 inch
600D Oxford with PVC coating
Two reinforced windproof straps
Pros
- Broad fit list across many 36 inch models
- Straps hold on a moving RV
- Folds compactly for RV or garage storage
- Reinforced stitching resists tearing
- Hose-off cleaning
Cons
- Does not fit the 36 inch Pro Series
- Cover usually has to come off to move the griddle
- Lower search rank than the other 36 inch covers
Packability is what separates this one. The cover folds down small enough for an RV, a garage shelf, or a camping bin, which matters if your griddle does not live permanently beside the house.
The fit list is genuinely wide for a 36 inch cover, spanning several Blackstone four-burner numbers, the 1819 charcoal combo, the 1868 air fryer model, Camp Chef FTG600, and a Weber model. At 4.6 stars across 2k+ reviews, the positives are compatibility, strap security, and packability.
Material is 600D Oxford polyester with a water-resistant PVC coating that resists sun, rain, snow, and temperature swings without rusting or fading. Two reinforced straps lock under the griddle, and reviewers specifically mention holding on a moving RV, which is a harder test than a patio.
Cleaning is hose-off and air-dry in the sun, and reinforced stitching handles the abrasion that comes from repeated folding and unfolding in a tight storage space.
Two limitations are worth weighing. It does not fit the 36 inch Pro Series, and in most setups the cover has to come off before the griddle can be moved, so it is a storage cover rather than a travel cover.
When folding size decides the purchase
If the griddle lives in a fifth wheel, a truck bed, or a storage container, folded volume is the metric that matters more than fabric weight. This cover stows flat and small, which is the reason owners with tight storage picked it over heavier alternatives.
Where it falls behind the field
Its review count and category ranking trail the other 36 inch covers in this roundup, and roughly 3 percent of reviews are one-star. If your griddle is the Pro Series, none of the features above apply, so look at a fit that includes your model number.
11. Comnova Cover for Traeger Flatrock – Best for Flatrock and BAC751 Griddles
Comnova Grill Cover for Traeger Flatrock – Premium Flat Top Griddle Cover for Traeger Waterproof & Heavy Duty, 600D Gas BBQ Cover Accessory for Treager Flatrock Flat Top Grills (BAC751)
47 by 27 by 40 inch
600D oxford cloth with PU coating
Adjustable hook-and-loop straps each side
Pros
- Made for the Traeger Flatrock and BAC751
- PU-coated 600D oxford
- UV tested to three years
- Quick-drying surface rinses clean
- Adjustable straps fit different sizes
Cons
- Velcro collects fuzz hair and dust
- Slightly loose fit on some models
- Thinner than OEM branded covers
Brand-specific covers for non-Blackstone griddles are rare, so a purpose-built one for the Traeger Flatrock is worth noting. It covers the Flatrock, the Flatrock 3 Zone, and the BAC751 model, measured at 47 by 27 by 40 inch.
At 4.7 stars across 2k+ reviews, the reviews concentrate on fit, the PU-coated 600D oxford cloth, and value against the OEM Traeger cover. The coating is both waterproof and UV resistant, and the fabric is tested to withstand more than three years of UV aging.
Securement uses adjustable hook-and-loop straps on each side, described as magic bands, which let you tension the cover across slightly different sizes. The quick-drying cloth rinses with water and dries fast, which is helpful for a cover that goes on damp more often than most.
Owners upgrading from an official cover generally see this as a good trade: comparable protection for less, with adjustable fit that an OEM molded cover cannot offer.
The two reported gripes are both about the closure and the cut. Velcro straps collect fuzz, hair, and dust over time, and some owners find the fit slightly loose on certain models. It is also thinner than an OEM branded cover.
Why a model-specific cover is worth buying
A form-fitting cover does not need to be large enough to fit anything, so it can be cut tighter and seal better against wind and rain. Owners comparing it to the Traeger OEM cover report the fit as close enough that the difference is mostly the price and the adjustable straps.
What to check on the fit
Confirm the vertical dimension, since 40 inch of height is generous and some users report a slightly loose result. Also expect to clean the hook-and-loop straps a few times a season, because grit in the hook is the main reason velcro closures lose grip first.
12. SHINESTAR Cover for Blackstone 36 Inch Without Hood – Best for No-Hood 36 Inch Griddles
SHINESTAR Griddle Cover for Blackstone 36 Inch Griddle Without Hood, Heavy Duty Waterproof Flat Top Gas Grill Cover with Click-Close Straps, UV-Resistant BBQ Cover for More 4-Burner Griddle
66.5 by 22.5 by 26 inch
Silver inner layer for UV defense
Windproof click-close straps
Pros
- Fits 36 inch griddles without a hood
- Waterproof coating with upgraded sewing
- Click-close straps hold during storms
- Inner silver layer reflects UV
- Works with other 4-burner brands
Cons
- Not compatible with the 36 inch Pro Series
- Hook-and-loop collects debris over time
- Some owners prefer buckle closures
A no-hood 36 inch griddle is the most common four-burner body, and this cover is cut for it at 66.5 by 22.5 by 26 inch. It also covers Camp Chef FTG 600 and Royal Gourmet four-burner flat tops, which widens its usefulness.
At 4.6 stars across 2k+ reviews, the reviews highlight the fit on no-hood 36 inch griddles, the waterproof protection, and the click-close straps holding in strong gusts. Owners returning to it after a few seasons rate the value highly for a cover at this tier.
The UV defense approach here differs from the others. Instead of adding a chemical stabilizer, it uses an inner silver fabric layer that reflects and blocks UV rays, layered inside a waterproof coating applied with an upgraded sewing technique.
Tear-resistant Oxford fabric with reinforced stitching handles abrasion, and the click-close straps at the bottom lock the cover firmly in place during storms rather than relying on a simple tie.
Two limits stand out. It is not compatible with the Blackstone 36 inch Pro Series, which is the most common fit complaint in its reviews, and the hook-and-loop closure collects debris over time like any velcro strap.
How a reflective inner layer helps
A silver inner layer works on UV rather than water. It bounces solar radiation back out instead of letting it reach the outer fabric, which slows the fading and the fiber breakdown that turns a black cover brittle and split after a few summers.
Who should look at a different cover
If you own a Pro Series, this is the wrong shape and no amount of adjustment will fix it. If you are in a high-wind location, note that owners who prefer buckles consider hook-and-loop the weaker choice, and the buckled covers in this roundup handle exposed sites better.
How to Measure Your Griddle Before You Buy a Cover
Measure the widest point of your griddle at the shelf tips, not the cook box. A 36 inch griddle is rarely 36 inches wide once the side shelves are attached, and that gap is the reason so many covers turn out to be a few inches short.
Then measure the height, including the hood, the handle, and anything standing proud of the body. Add 2 to 4 inches to both numbers before you compare against a cover’s stated dimensions.
Check the cover’s published dimensions, not the griddle size in the title. Brands use the griddle number as a label, and a cover advertised for a 36 inch griddle may be cut to fit a 36 inch body without shelves.
A tape measure and two minutes beat a return shipment every time. Most of the one-star reviews in this roundup trace back to a fit that was assumed rather than verified.
What Cover Material Actually Blocks Water
The best material for an outdoor grill cover depends on whether water sits on it or soaks through it. Three constructions cover almost every option in this roundup.
600D and 1000D polyester canvas with a waterproof backing or coating is the workhorse. The denier number is thread thickness, so 1000D is roughly twice as tear and abrasion resistant as 420D or 600D, which is why it lasts longer in high-wind and heavy-handling situations.
PU and PVC coated oxford or ripstop is the lighter, shinier option. It sheds water reliably and dries fast, which is useful for a cover that goes on damp, but the coating is the first thing to degrade under sustained UV.
Hard molded or formed shells do not absorb water at all. There are no seams to fail and no fabric to fade, which is why owners in colder regions treat a rigid lid as the strongest long-term option.
On waterproofing specifically, sealing tape over a stitched seam matters more than the coating on the face fabric. Water finds seams first, and a taped seam stays closed where a stitched-only seam eventually wicks.
Hard Cover vs Soft Cover: Which One Protects a Griddle Better
A hard shell wins on long-term exposure. It cannot be lifted by wind, it cannot trap condensation under a hem, and it has no fabric to fade, so it protects a griddle through multiple seasons without replacement.
A fabric cover wins on everything else: price, weight, packability, and the ability to fit more than one griddle body. It also conforms to shelves and hoods that a rigid lid cannot.
Forum owners consistently describe the OEM hard lid as the better choice for low-temperature storage and for trapping heat in, and a fabric cover as the better choice for a griddle that moves.
Wind Securement: Why Covers Blow Off and How to Stop It
Covers do not blow away because of weak fabric. They blow away because wind gets under an edge and levers the whole panel up, and every failure starts at the bottom hem.
Plastic buckles that clip under the griddle base are the strongest mechanism, and the base-anchored OEM covers use them for that reason. Where the base is not accessible, two side straps plus four bottom buckles achieve the same result by closing the gap along its full length.
A drawstring hem is a good second layer, and hook-and-loop is a weak one. Velcro collects grit, then UV makes the hook brittle, and the strap stops holding by the third season in full sun.
Look for vents too. A cover that billows generates force across the whole panel, so structured side vents and leg-level anchor cords reduce the load on the fabric as well as the lift underneath it.
Dry the Griddle First: The Step Most People Skip
A cover only protects an already dry, already cool griddle. Cover a hot or damp surface and you are sealing moisture against bare rolled steel, which is the leading cause of the surface rust that shows up under a cover that was supposed to prevent exactly that.
So the sequence matters. Let the griddle cool completely, wipe off grease, dry the cooking surface, then fit the cover and secure it. Wiping the surface is not optional, since a thin film of grease holds moisture against the steel.
Do the same before storing a folded cover. Dry it first, fold it loosely rather than tight, and keep it somewhere ventilated. A cover packed damp in a bin will smell for a season and the mildew will not wash out.
For the same reason, check your cover for vents. A tight unvented cover over a barely damp griddle can hold condensation for days, and the same is true of a hard lid set down on a surface that is not ventilated underneath.
Can You Leave a Griddle Outside Year-Round Under a Cover?
Yes, and most owners do. A covered griddle handles rain, snow, sun, dust, insects, and bird droppings far better than an uncovered one, and it removes the biggest annoyance of outdoor cooking, which is moving a heavy appliance indoors after every cook.
The conditions are simple. The cover has to fit, the griddle has to be dry and cool when you put it on, and it has to be secured so wind cannot get underneath. Miss the third one and you will find the cover somewhere down the block after the first storm.
Where owners hesitate is full-time exposure in high-sun or coastal locations, because fabric fades and a hard lid does not. A rigid shell is the answer for a permanent outdoor spot, and a fabric cover with a good UV rating is the answer for a covered patio or a garage-adjacent slab.

Frequently Asked Questions
What is the best griddle cover?
For most 36 inch griddles the factory-fit Blackstone 36 Inch Griddle Cover is the best choice, because 600D polyester with poly-resin buckles that clip under the base is the construction that survives wind. If you own several brands of four-burner griddle, the iCOVER 36 Inch Griddle Cover fits more bodies at once. For a 28 inch griddle with a hood, the Blackstone 5483 cover is the strongest owner-matched option.
Can you leave a griddle outside with a cover?
Yes, a covered griddle handles rain, snow, sun, dust, insects, and bird droppings far better than an uncovered one. The cover has to fit, the griddle has to be fully cool and dry when you put it on, and it has to be buckled or strapped so wind cannot get under the hem. For a permanent exposed spot, a rigid hard shell outlasts any fabric.
What is the best material for an outdoor grill cover?
It depends on how the water reaches the fabric. 600D or 1000D polyester canvas with a waterproof backing is the most durable all-round option, and 1000D is rated at roughly twice the tear resistance of 600D. PU and PVC coated oxford sheds water reliably but degrades under sustained sun. A hard molded shell does not absorb water at all and lasts longest.
What is the best waterproof grill cover?
For waterproofing, look at the seam rather than the face fabric. Hot-melt seam sealing tape over a waterproof vinyl lining holds water out where a stitched-only seam eventually wicks, which is why the Unicook 28 inch cover performs well in heavy rain. The iCOVER and Onlyfire covers add a PVC coating on top of that for covered four-burner bodies.
Should a grill cover be waterproof?
Yes, water resistance is worth having on any griddle stored outdoors, but waterproof fabric does not fix a wet griddle. Moisture sealed against bare steel causes the surface rust a cover is supposed to prevent, so let the griddle cool, wipe the grease, dry the surface, then cover it. Choose a cover with a vent so trapped moisture can escape between rains.
How much bigger should my grill cover be than my grill?
Add 2 to 4 inches in every direction. Measure the widest point at the shelf tips rather than at the cook box, and measure the height including the hood and handle, because a 36 inch griddle is rarely 36 inches wide with shelves attached. Compare those numbers against the cover’s published dimensions instead of trusting the griddle size in the listing title.
The Best Griddle Covers for Outdoor Storage in 2026
The best griddle covers for outdoor storage in 2026 split cleanly by fit. The Blackstone 36 Inch Griddle Cover is the pick for a 36 inch station with shelves, and its base-clipping buckles solve the wind problem that ruins most fabric covers.
The iCOVER 36 inch cover covers the most griddles in one buy, and the Blackstone 5483 cover is the right call for a 28 inch model with a hood. The Flybold hard shell wins for a permanent exposed spot, where a fabric cover will fade and a rigid lid will not.
Whichever one you pick, dry the griddle before you cover it and secure the bottom edge every time. That habit matters more to how long your griddle lasts than any single feature on the listing.
