Buying Guide: How To Choose An Extra Large Barbecue Cover
- Fit and dimensions: Measure your grill’s length, width, and height. Choose a cover that offers at least 1-2 inches of clearance on each dimension to accommodate accessories and tapering shapes.
- Material and waterproofing: Look for 600D or higher Oxford cloth or polyester with a waterproof coating. Consider UV resistance for sun-exposed regions and tear resistance for windy climates.
- Wind resistance: Features like Velcro straps, buckles, adjustable drawstrings, and air vents help prevent cover displacement and condensation inside.
- Island vs. cart-style grills: Island covers are larger and require deeper depth and height coverage. Check for venting and securing hardware to minimize wind lift on island configurations.
- Seasonal use: All-season protection benefits grills stored outdoors year-round. If you store indoors, simpler covers may suffice, but outdoor coverage offers longer grill life.
- Maintenance: Choose materials that are easy to wipe clean and quick-drying. Some fabrics resist mold and mildew better than others.
