Crafted in the USA, our American Flagship Ripstop boat cover is made from a ripstop polyester fabric that will provide your boat with optimum protection from the elements. This cover is made from 3 heavy duty layers. The outer ripstop layer is waterproof with a UV resistant finish, so your boat will be protected rain or shine. The middle layer is made from a waterproof, yet breathable membrane, to create effective air flow. The inner most layer is nonabrasive and the microfiber fleece will help protect your boat from dings and scratches. This cover has a sewn in venting system that allows an ample amount of air to flow through the cover, which helps prevent billowing. A top and bottom buckle and strap system is included to keep your cover secure in windy conditions.
