10 Best Heavy Duty Grill Covers 2025 in the United States

The iCOVER 36 inch Griddle Cover is designed to fit most 4-burner flat top grills, especially popular models from Blackstone, Weber, and Camp Chef. Its size (66.5" x 22.5" x 35") covers your griddle well, though it doesn’t fit the Blackstone 36” ProSeries. Made from heavy-duty 600D oxford polyester with a waterproof PVC coating, it provides strong protection against rain, snow, wind, and sun thanks to UV resistance and reinforced corners that resist tearing. An added support pole prevents water pooling on the cover, which helps keep your grill dry and clean.

The cover also features straps and buckles on the sides and bottom, so it stays secure even in windy weather. For convenience, it has padded handles to make putting it on and taking it off easy, and the material is simple to clean with just a hose-down. While the material is durable, canvas polyester can wear faster than some higher-end vinyl covers in very harsh conditions. Additionally, it’s designed mainly for flat top grills, so it might not fit other grill shapes well.

If you want a sturdy, waterproof cover with good ventilation and solid wind protection, this cover provides a reliable option that helps protect your grill year-round without much hassle.

The Unicook 52 Inch Grill Cover is designed for grills like the Weber Spirit 200 and 300 series, offering a good fit for many 2-3 burner grills up to 50 inches wide. Made from heavy-duty polyester with a waterproof vinyl coating, it protects well against rain, UV rays, and general wear, helping to keep your grill safe from weather damage. Its fade-resistant fabric means the cover should keep looking good over time despite sun exposure.

The cover has sturdy straps to keep it securely in place, which is helpful on windy days, and durable handles make it easier to put on, remove, or hang for storage. Cleaning is simple—just rinse with water and air dry, although it’s not machine washable. Compatibility is important to note as it doesn’t fit all Weber models, especially Spirit II 300 and some older ones, so measuring your grill before buying is recommended.

With a snug fit and durable materials, this cover is suitable for keeping moisture out and prolonging your grill’s life. It is a solid choice if you want a heavy-duty, weather-resistant grill cover that’s easy to handle and built to last, but be sure to double-check your grill’s size and model to ensure proper fit.

The Unicook 58 Inch Grill Cover is designed specifically for Weber Genesis and similar sized grills, making it a versatile choice for various brands with 3-5 burners. One of its notable strengths is the construction material; it's made from a heavy-duty, fade-resistant polyester fabric with a waterproof vinyl coating, which ensures durability and protection against the elements such as rain and cold. This can be beneficial in extending the life of your grill by shielding it from harsh weather conditions. However, it is important to note that it does not fit Weber's 2022 Genesis 300 series grills, so be sure to measure your grill before purchasing to ensure a proper fit.

The grill cover is also wind-resistant thanks to its sturdy hook and loop fasteners, preventing it from blowing away. Additionally, it features durable handles that make it easy to put on and take off, and these handles can also be used for convenient storage. On the downside, while the cover is easy to clean by simply hosing it down, it is not safe for washing machines or dryers. This may be a minor inconvenience for some users.

The product appears well-suited for anyone looking to protect their grill from the elements while also seeking ease of use and durability. It is lightweight at just under 4 pounds, which makes it manageable for most users.
