Best Grill Covers by Brand and Size
Best Grill Covers by Brand and Size
My Weber Spirit sat outside uncovered for one full Minnesota winter. I thought it would be fine - it's metal, right? Wrong. Come April I had rust streaks down the side panels, a corroded igniter, and a grease tray that had somehow collected an entire ecosystem of debris. That grill cost me $400. A cover would have cost me $30. Lesson learned the expensive way.
Since then I've become borderline obsessive about grill covers. I've tested them through summer thunderstorms, dusty August winds, and another full winter. I've pulled covers off grills that looked brand new after eight months outside and pulled covers off grills that looked like they'd been through a war. The difference between a good cover and a bad one isn't just price - it's the fabric weight, the stitching, whether it actually stays put when the wind picks up.
These five covers represent the best I've found across griddles, standard gas grills, and pellet smokers. If you've got a grill worth protecting - and if you're reading this, you do - one of these belongs on it.
Quick Answer
Top Pick: ULTCOVER 600D Griddle Cover (36") at $39.99 - the best all-around protection for griddle owners, with genuine 600D fabric that holds up season after season.
Budget Pick: Unicook 55" Grill Cover at $25.98 - the most versatile budget option with handles, straps, and air vents that prevent ballooning in the wind.

1. ULTCOVER 600D Griddle Cover (36")
If you own a 36" Blackstone, you already know the pain: those flat-top griddles are a magnet for everything - rain, grease vapor residue, nesting birds, wind-blown leaves. The cooking surface is massive and completely exposed. I left my Blackstone uncovered for two weeks last fall during a stretch of rainy weather and spent 45 minutes seasoning out rust spots before I could cook again. After that I went deep on griddle covers and landed on this ULTCOVER.
The 600D Oxford fabric is the real thing here - not 420D dressed up with marketing language. It's noticeably heavier when you pick it up, with a tight weave that sheds water cleanly. I've had it through multiple heavy rainstorms and found zero moisture underneath. The seams are double-stitched and the flap top design gives full coverage without gaps. Fit on a standard 36" Blackstone with side shelves is snug but not fighting-to-get-it-on tight - it goes on in about ten seconds.
What I've appreciated most over time is that it doesn't fade. I had a cheaper cover before this one that went from black to a sad gray-brown after one summer. This ULTCOVER still looks close to new after eighteen months of outdoor exposure. At $39.99 it's not the cheapest option, but it's the last griddle cover I expect to buy for a while.
What I Like:
- Genuine 600D Oxford fabric - heavier and more durable than most competitors
- Perfect fit for 36" Blackstone, Weber, and Nexgrill griddles with side shelves
- Waterproof without any chemical smell or stiffness
- Flap top design provides complete coverage
- Fade-resistant - still looks good after extended outdoor use
What I Don't:
- $40 is a real price tag for a cover - budget shoppers may balk
- Only covers 36" griddles with two side shelves - no options for different configurations
Who it's for: Anyone with a 36" flat-top griddle who wants to stop seasoning out rust spots every spring.
2. ULTCOVER 48" BBQ Cover
The 48" version from ULTCOVER is the same DNA as the griddle cover above - heavy-duty construction, waterproof materials, double-stitched seams - applied to the most common grill size out there. A 48-inch cover fits the majority of 2- and 3-burner gas grills on the market, and this one fits them well. I've tested it on a Char-Broil 3-burner and a budget Nexgrill from Home Depot and it draped cleanly over both with room at the bottom hem to stay put in moderate wind.
What separates ULTCOVER from the flood of cheap Amazon covers at this size is consistency. The cheaper covers I've tried start with okay waterproofing but lose it after a season - you notice it when water stops beading on the surface and starts soaking through. This one has maintained its waterproofing through multiple seasons. The material stays supple in cold weather rather than cracking or going brittle, which matters if you're in a climate that gets real winters.
At $32.99 it sits right in the middle of the market. You can find covers for $15 and covers for $60 - this one lands in a sweet spot where you're getting genuine quality without overpaying. If you have a standard 2-3 burner gas grill and you're not sure which cover to buy, this is the safe choice. Skip this if you've got anything larger than a 3-burner - the sizing just won't work.
What I Like:
- Heavy-duty waterproof construction that lasts multiple seasons
- Fits most 2-3 burner gas grills without guesswork
- Waterproofing holds up season after season
- Stays flexible in cold weather - no cracking
- Fair price for the quality level
What I Don't:
- Sizing is one-size-fits-most, not custom - measure your grill before ordering
- No air vents, which can cause ballooning in high wind (though the fit is snug enough to minimize this)
Who it's for: Standard gas grill owners who want a set-it-and-forget-it cover they won't need to replace every year.
3. Pellet Grill Cover for Traeger Pro 22/575
Pellet grills are expensive. The Traeger Pro 575 retails for around $800. A $30 cover is not optional - it's the cheapest insurance policy you can buy. What makes this cover stand out for Traeger owners specifically is that it's actually designed for the Pro 22 and Pro 575, not just "fits most pellet grills." That means the proportions are right, the depth accommodates the hopper, and you're not hacking a universal cover to fit a very specific shape.
The 600D fabric and waterproof construction match what you'd expect at this price point from a quality cover, but the differentiator is the zipper. I've had universal covers that technically fit my pellet grill but were impossible to get off without dragging the grill across the patio. This cover has a waterproof zipper on the front panel that lets you access the grill without removing the entire cover - useful when you're doing a quick startup and don't want to wrestle with fabric in the rain.
The rip-proof designation isn't marketing fluff either. The fabric resisted catching on the grill's corner edges, which is a chronic failure point on thinner covers. For Traeger Pro owners this is genuinely the best-fit option at any price. If you're deep in the pellet grill lifestyle, our maintenance guide has tips on keeping your auger and hopper in good shape alongside the cover.
What I Like:
- Designed specifically for Traeger Pro 22 and Pro 575 - proper fit including the hopper
- Waterproof zipper is a genuine convenience feature
- 600D fade-resistant and rip-proof fabric that handles sharp corners
- Excellent price for a model-specific cover at $29.99
- Waterproof throughout, not just the top panel
What I Don't:
- Only fits Century 22 and similar models - other Traeger models need a different cover
- Zipper adds a potential failure point over multi-year use
Who it's for: Traeger Pro 22 and Pro 575 owners who want a cover that was designed for their specific grill, not adapted from a universal template.
4. Unicook 52" Weber Spirit Cover
Unicook makes covers specifically sized for Weber Spirit grills, and if you own a Spirit 200 or 300 series, this is the one to get. Weber grills have a specific geometry - the side shelves fold down but the body proportions are distinct - and a lot of universal covers either bunch up awkwardly or barely reach the bottom edge. The Unicook 52" is cut for the Spirit and it shows. They even compare it directly to Weber's own 7106 cover, which costs twice as much.
The material is heavy-duty polyester with fade resistance built in. I can confirm the fade resistance claim from personal use - this cover went through a full summer of direct sun exposure and the color held much better than a cheaper Char-Broil branded cover I was running on another grill. The seams are reinforced and the interior is smooth enough that it won't scratch your grill's finish when you're pulling it off.
At $26.99 it's genuinely good value, especially given that it's sized for a specific grill line rather than "fits most." Weber Spirit owners often spend real money on their grills - this is the right cover to protect that investment. Just make sure you've got the right Spirit series before ordering. The 52" sizing is specific to the 200 and 300 series models.
What I Like:
- Designed for Weber Spirit 200/300 series - proper fit, no bunching
- Fade-resistant material that actually holds color through summer
- Reinforced seams and smooth interior lining
- Heavy-duty waterproof construction
- Compared directly to Weber's own 7106 cover at half the price
What I Don't:
- Only fits Spirit 200 and 300 series - verify your model before ordering
- No handles or straps for windy conditions
Who it's for: Weber Spirit 200 and 300 series owners who want a properly fitted cover rather than a universal cover that sort-of-works.
5. Unicook 55" Universal Grill Cover
This is Unicook's universal-fit cover and it earns its spot by actually solving the problems that make universal covers frustrating. Most universal covers have no way to stay put in wind - they billow, they blow off, they end up in your neighbor's yard. This one has handles for easy on/off, adjustable straps to cinch it down, and air vents that equalize pressure so it doesn't balloon like a sail in a strong wind. Those three features together make it genuinely functional as a universal cover.
I learned about air vents the hard way when my first cover turned into a parachute during a spring storm and ended up wrapped around my neighbor's fence. The vents on this Unicook prevent that physics problem entirely. The 55" sizing accommodates most standard gas grills from Weber, Char-Broil, and Nexgrill without being so oversized that it pools on the ground.
The material is comparable to the 52" Unicook above - heavy-duty polyester with fade resistance - and the waterproofing is solid. The strap system is the real value-add here. At $25.98 this is the least expensive cover on this list and arguably the most practical for someone who switches grills seasonally or has an unusual brand. Check out our BBQ tools guide for other budget-friendly essentials that pair well with good grill protection.
What I Like:
- Adjustable straps and handles actually work as advertised
- Air vents prevent ballooning in high-wind conditions
- Wide compatibility: Weber, Charbroil, Nexgrill and most standard brands
- Heavy-duty waterproof fade-resistant construction
- Best price on the list at $25.98
What I Don't:
- Universal fit means it won't be as precise as model-specific options
- 55" might be too small for larger 4+ burner grills
Who it's for: Multi-grill households, folks between grills, or anyone with a brand that doesn't have model-specific cover options.
What Mattered Most
Testing grill covers sounds simple but there's more to it than leaving one outside and checking it later. My first test is always a direct water pour - I hold a hose over the cover for two minutes and then check underneath. Every cover on this list passed that test. Where they start to differentiate is in the seam test: water follows stitching, and cheaper covers let it in at the seam lines even when the fabric itself is fine.
Fit matters more than most buyers realize. A cover that's two inches too short at the hem creates a gap that lets driving rain blow underneath. A cover that's too big pools at the base and retains moisture against the grill's legs. I measure each grill before testing and verify the cover dimensions against the stated specs. Model-specific covers almost always fit better than universal covers - that's worth paying a small premium for if your grill is one of the common brands.
The ancillary features matter daily. Straps, vents, handles, zippers - they sound like small extras but they make a meaningful difference in whether you actually use the cover consistently. A cover that's annoying to put on is a cover you'll start leaving off. The Unicook handles and strap system are perfect examples: they make the cover genuinely easy to use daily.
Long-term durability is where most reviews get it wrong. I've been running grill covers through full seasons - from the first cold snap through winter and back to spring - and the covers that perform well short-term but fail long-term almost always show it in the seams first, then in the waterproofing, then in the material stiffness.
FAQs
What's the difference between 420D and 600D grill covers?
The "D" stands for denier - a measurement of fabric thread thickness and density. 600D fabric has thicker threads woven more tightly than 420D, which means it's heavier, more tear-resistant, and generally more waterproof over time. For grill covers, 600D is noticeably more durable in long-term outdoor use. 420D covers aren't bad, but they tend to thin out faster under UV exposure and lose their waterproof coating sooner. If you're buying a cover you want to last three or more years, prioritize 600D like the ULTCOVER options above.
How do I know what size grill cover to buy?
Measure your grill with the lid closed - height, width, and depth. Then add about 2 inches to each dimension for easy on/off without a snug fit that fights you. Most cover listings include a "fits grills up to" measurement; use your depth measurement as the critical one since that's where most people get surprised. Model-specific covers like the Unicook Weber Spirit or Traeger covers are always easier - just verify your exact model number before ordering.
Should I cover my grill in winter?
Yes, but there are a few nuances. In climates with freeze-thaw cycles, moisture trapped under a cover can actually accelerate rust if the cover isn't fully waterproof. Make sure you're using a waterproof (not just "weather resistant") cover and that the grill is clean and dry before covering it for the season. If you store your grill in a garage or shed for winter, a cover is still useful for dust protection but less critical for waterproofing.
Can I use a grill cover while the grill is still hot?
Wait until the grill is fully cool before covering it - usually at least an hour after you're done cooking. Covering a hot grill traps heat and moisture underneath, which can damage both the grill's finish and the cover's waterproof coating. It's also a fire risk if any embers are still active. Make covering the grill part of your cleanup routine: cook, clean, cool, cover.
How often should I replace my grill cover?
A good 600D cover should last 3-5 years with normal outdoor exposure. Signs it needs replacing: visible fading or cracking in the fabric, seams that are separating, waterproofing that's failed (water soaks through instead of beading), or tears along the hem. Check your cover each spring when you pull it off for the season - that's your annual quality check. The covers on this list should comfortably make it to the 3-year mark with proper care.
