The Cushion Storage Bag is part of our premium StormBlock Hillside collection. The last word in style, durability and all-weather protection, our StormBlock Hillside covers are beautifully designed with an elegant black and tan weave pattern with tan piping that will complement any patio decor. Meanwhile, double-stitched seams keep your patio furniture dry and built-in straps, buckles and an elastic hem keeps them secure in windy conditions. The StormBlock Hillside collection is constructed from our strongest, most reliable 1200 denier polyester. Waterproof by itself, this material is then treated with RustOleum StormBlock, a hydrophobic coating that makes our covers 100% waterproof, weatherproof, stain-resistant and UV-resistant. For those wanting the quality covers that will protect their patio collection for years to come, the StormBlock Hillside collection is for you. In fact, we believe in these patio furniture covers so much, every cover in this collection comes with a 7-year warranty.
