You simply won't find a better cover to protect your boat. Sun Armor covers are constructed of a polymer-impregnated, 100% polyester fabric. Tests have proved that this is one of the strongest, most airtight fabrics available -- extremely water-repellent, colorfast, UV-resistant, and durable. It has the highest tear strength when compared to similarly priced fabrics. A strong, braided rope is sewn into the hem for a tight fit against the hull, and every top seam is reinforced with sewn-on 1'' poly-web straps to add strength. Includes snap-buckle tie-downs that pull the cover down to reduce wind bagging and fluttering while trailering. Includes a separate motor hood for a tailored fit. Includes manufacturer's 5-year warranty. Made in USA. For more information on sizing and selecting a boat cover, read our Boat Cover Buyer's Guide .
