This Deluxe Cover is made from a new patented three-layer composite fabric. It contains a microporous film sandwiched between two layers of soft and tough, water-repellent polypropylene. The microporous film has pores that allow moisture vapor to escape while impeding liquids and particles from passing through. The excellent design prevents mold, mildew and ice buildup. Include Storage Bag and Cable Lock Kit. Not machine wash or dry-able.
