Weber Grill Cover Buyer's Guide: Find the Right Fit

Leaving a grill uncovered through Ohio winters , or even a wet spring weekend , is how you turn a quality piece of equipment into a rust problem. A good Tools & Grates setup only stays that way if you protect it between cooks, and that starts with a cover that actually fits. The right cover depends almost entirely on which grill you own, so that’s the frame this guide uses.

There are a lot of covers on the market claiming to fit “most grills.” Most of them fit most grills the way a hotel shower cap fits most heads. This guide covers four options sized for two specific grill families , the Weber Genesis II series and the Weber 22-inch Kettle , so you can match to what you actually own.

What to Look For in a Weber Grill Cover

Fabric Weight and Weather Resistance

Cover fabric is rated by denier , a measurement of thread density and thickness. Higher denier means heavier, more abrasion-resistant fabric. Entry-level covers typically use 300D polyester, which handles light rain and dust but shows wear after a season or two of real exposure. Covers in the 600D, 800D range are meaningfully more durable , they resist tearing, shed water more aggressively, and hold up longer in direct sun.

Waterproofing is a separate property from fabric weight. A cover can be heavy and still wick moisture if the waterproof coating has degraded. Look for covers that specify a waterproof coating treatment, not just “water-resistant.” The difference matters most if you leave the grill outside year-round rather than storing it seasonally.

Fit: Specific vs. Universal

Universal covers are sold by approximate dimensions , “fits grills up to 60 inches wide,” for example. They work, with caveats. Side shelves, cart handles, and side burner knobs create gaps at the bottom edge where wind can work the cover loose and where rain can pool and drain inside. A cover designed for a specific grill family , Genesis II, for instance , is cut to account for those protrusions.

Fit precision matters more in high-wind environments than in sheltered locations. If your grill lives in an exposed area, a snug, form-fitted cover with tie-down straps or a hem cord is worth prioritizing over a generic option that requires frequent readjustment.

UV and Fade Resistance

Sun damage is slower than rain damage but equally cumulative. Polyester covers without UV inhibitors become brittle after two or three seasons of direct exposure , seams split, fabric chalks, and the waterproof coating delaminated from the underlying material. Covers marketed as “fade resistant” have UV stabilizers worked into the fabric or coating. This is a meaningful feature in climates with long, sunny summers, and also in situations where your grill faces south or west without shade.

Browsing the full range of Weber grill accessories and covers is worth doing before you buy , knowing what else pairs with your setup can save you a separate purchase later.

Secure Closure and Ventilation

A cover that blows off in the first thunderstorm is not protecting your grill. Hem drawcords and buckle straps are the two most common secure-closure mechanisms. Drawcords work well for kettle covers where the grill silhouette is roughly conical; straps work better for rectangular gas grill covers where the wind can catch a flat vertical surface.

Ventilation is less commonly discussed. Covers without airflow panels trap condensation , particularly in humid climates , which can accelerate rust on cast iron grates and corrode burner tubes from the inside. Small mesh vents on the upper section of a cover address this without compromising weather protection meaningfully.

Top Picks

Kingkong 7130 Grill Cover for Weber Genesis II 3 Burner

The Kingkong 7130 Grill Cover for Weber Genesis II 3-Burner Grills earns the top spot for Genesis II and Genesis 300 series owners because it’s engineered to fit those specific grills , not “grills in a similar size class.” The model number alignment with Weber’s own 7130 spec means you’re getting a cover cut to account for the Genesis II’s side burner shelf, handle profile, and cart footprint rather than one that approximates the shape.

The bundle inclusion of a brush, tongs, and thermometer is either genuinely useful or completely irrelevant depending on where you are in your gear acquisition. If you’ve already got quality tools, these don’t move the needle. If you’re newer to the setup, getting them included with the cover rather than sourcing them separately is a reasonable convenience. The cover itself is the reason to buy this; the accessories are a bonus, not the pitch.

The Kingkong is the right answer for Genesis II 3-burner owners who want a precise fit without spending premium prices. It covers the 300 series broadly, so if you’re on an older Genesis 300 or a current Genesis II E-315, it’s the same cover doing the same job.

Upgraded 800D Heavy Duty Fabric 58” Grill Cover for Weber Genesis II

The Upgraded 800D Heavy Duty Fabric 58” Grill Cover is the choice when weather protection is the primary concern and you’re willing to trade some handling convenience for heavier, more durable material. At 800D, this fabric is noticeably denser than standard entry-level options , the kind of cover that doesn’t flutter in a stiff wind and doesn’t develop surface pilling after one winter.

The 58-inch sizing covers Genesis II and LX 300 series grills with appropriate clearance. The tradeoff of heavier fabric is real , folding and storing this cover takes more effort than a lighter option, and pulling it on and off in wet weather is less pleasant. That’s not a fatal flaw; it’s a deliberate material trade-off. If your grill stays outside through hard weather and you pull the cover off twice a week all season, you’ll feel the weight. If it primarily sits through long storage periods, the 800D construction is exactly what you want.

For Genesis II owners who prioritize durability and are prepared to handle the added weight of a proper heavy-duty material, this is the strongest choice for year-round outdoor storage.

iCOVER Grill Cover for Weber 22 Inch Charcoal Kettle

Kettle owners have different cover geometry needs than gas grill owners, and the iCOVER Grill Cover for Weber 22 Inch Charcoal Kettle is designed around that specific shape. The Weber 22-inch kettle is one of the most common grills in American backyards , including mine , and covers designed for the kettle profile fit the bowl, lid, and cart legs correctly rather than draping loosely over them.

Heavy duty waterproof construction means this handles rain without the fabric wicking moisture down toward the bowl. The compatibility with Char-Broil 22-inch models broadens its usefulness if you’re covering a kettle that isn’t Weber-branded but shares the same dimensions , a reasonable and practical note, not a marketing stretch.

Periodic fit adjustment is normal with kettle covers because the conical shape doesn’t give the cover a rigid structure to wrap around. That’s not a deficiency specific to this cover; it’s a kettle geometry reality. A drawcord or strap keeps it in place through wind without much fuss.

Suphomeware 22 Inch Grill Cover for Weber Kettle Charcoal

The Suphomeware 22 Inch Grill Cover for Weber Kettle Charcoal earns its spot as the alternative kettle cover pick primarily on the fade resistance specification. Waterproofing and heavy-duty fabric are table stakes in this category at this point , the distinction is in how a cover holds up over multiple seasons of sun exposure, and Suphomeware explicitly addresses UV degradation in the material treatment.

For a Kettle that lives on a south-facing or west-facing patio without shade cover, that UV resistance matters more than it might seem. Standard polyester covers in constant direct sun start showing chalking and brittleness within two seasons. A cover treated for fade resistance extends the useful life meaningfully.

The one-size design limits this to Weber Kettle applications , it’s not trying to be universal, which is honest positioning. If your kettle isn’t a standard 22-inch Weber, verify dimensions before ordering. For standard 22-inch Kettle owners wanting a durable option with above-average sun protection, this is a sound choice.

Buying Guide

Genesis II or Kettle: Match the Cover to the Grill Family

The single most important purchase variable is grill family. Genesis II and Genesis 300 series grills are rectangular gas grills mounted on cart-style bases with side shelves and often a side burner. Weber 22-inch Kettles are round, cart-mounted charcoal grills with a completely different cover geometry. Buying a cover sized for one when you own the other doesn’t work , it’s not a close-enough situation.

Check your grill model number before buying. Weber’s model numbers are on the grill’s label near the burner controls or on the cart frame. Genesis II models start with E, EP, S, or SP designations. Kettle models are identified by bowl diameter.

Fabric Weight: What You Actually Need

800D fabric is heavier and more durable than 300D. That matters most if your grill is outside year-round and you’re in a climate with hard winters, extended rainy seasons, or intense summer sun. If your grill is stored in a garage from November through March and you only need cover protection for the grilling season, a lighter fabric still provides adequate protection and is easier to handle daily.

Honest assessment: most weekend grilling households in moderate climates will be well-served by mid-weight fabric. The 800D option is for the grill that genuinely lives outside, uncovered by a structure, through whatever the weather does.

Fit Precision vs. Universality

For the grill families covered here, fit-specific covers are available and worth choosing over universal options. Universal covers typically list compatible dimensions as a maximum , your grill might fit, or it might leave gaps that wind exploits. Model-specific covers are cut around the actual protrusions of a particular grill design.

The broader question of how covers fit alongside other grill protection equipment is worth exploring in the grilling tools and accessories section , grill mats, grate brushes, and storage options all interact with your overall setup.

Closure Systems and Wind Performance

Drawcords work better on kettle covers. Buckle straps work better on rectangular gas grill covers. The reason is surface area and wind behavior: a rectangular gas grill cover has a large flat vertical surface that wind can push under. A strap cinched under the cart lip resists that. Kettle covers sit over a curved surface that self-centers to some degree; a drawcord at the hem keeps it snug without requiring a rigid strap attachment point.

If your grill is in an exposed location , a rooftop deck, an open backyard without windbreak , closure quality should weigh more heavily in your decision than it would for a sheltered patio placement.

Condensation and Ventilation

This is the buying consideration most product listings underemphasize. A sealed cover in a humid climate traps moisture inside. That moisture settles on grill grates and burner tubes overnight, accelerating rust on cast iron components and corroding steel parts that weren’t designed for prolonged wet contact. Small mesh ventilation panels on the upper portion of a cover allow air circulation that manages this without meaningfully compromising weather protection.

If you’re grilling regularly and the cover goes on while the grill is still warm, ventilation matters more , a hot grill produces condensation as it cools inside a sealed cover. Let the grill cool fully before covering when possible, and prefer a vented design if your grill sees regular use through humid months.

Frequently Asked Questions

Do I need a different cover for a Weber Genesis II than for a Weber Kettle?

Yes, the grill shapes require different cover geometries. Genesis II grills are rectangular, cart-mounted gas grills with side shelves and a specific cabinet profile. Weber Kettles are round charcoal grills with a conical shape. A cover designed for one will not fit the other correctly , sizing is incompatible in both dimensions and silhouette.

What does 800D fabric mean and is it worth it for a grill cover?

Denier (D) measures the thickness and density of fabric threads , higher numbers mean heavier, more abrasion-resistant material. Standard covers use 300D polyester; the Upgraded 800D Heavy Duty Fabric cover uses significantly denser construction. It’s worth the added weight if your grill stays outside year-round through hard weather. For seasonal storage or moderate climates, mid-weight fabric performs adequately and handles more easily.

How do I know if a grill cover will fit my specific Weber Genesis model?

Check your grill’s model number on the label near the controls or on the cart frame, then cross-reference it against the cover manufacturer’s compatibility list. Genesis II models begin with E, EP, S, or SP designations followed by a three-digit number. The 300 series designation means a 3-burner configuration. Both the Kingkong and the 800D heavy-duty cover explicitly list Genesis II 3-burner and Genesis 300 series compatibility, which covers the most common configurations.

Can I leave a grill cover on when I’m grilling frequently, or does it need to come off completely?

The cover needs to come off before lighting the grill , always. Beyond that, frequent use actually reduces the risk of condensation buildup that can occur when a cover sits sealed for weeks in humid conditions. If you’re grilling twice a week, the cover is doing its job during the days between cooks. The main adjustment for frequent users is letting the grill cool completely before re-covering to reduce internal condensation.

Is fade resistance in a grill cover worth paying attention to, or is it mostly marketing?

Fade resistance is a real material difference, not marketing language. UV exposure breaks down standard polyester fabric , the coating delaminates, the material becomes brittle, and seams split. A cover with UV stabilizers in the fabric or coating, like the Suphomeware 22 Inch Grill Cover, holds up substantially longer in direct sun. It matters most for grills in unshaded, south- or west-facing locations through multiple seasons.
