The advanced engineered triple-layer ripstop polyethylene cover is built to stand up to the harshest elements. It is heat-sealed, not stitched, for superior waterproofing and UV-treated inside and out to resist fading, aging and staining for a beautiful look for years to come. The Skin Cancer Foundation recommends this fabric as an effective UV protectant.

Ratchet-Tite Cover Tensioning System
