SurLast is a 100% solution-dyed all weather polyester designed specifically for the special stress that boat covers endure. A urethane coating is added to one side adding stability, increased water and mildew resistance, and minimal shrinking or stretch. Colors will not fade or wash out. Use for trailering boat covers, PWC covers, equipment covers, and bags. 7 oz. per square yard. 3 year manufacturer's warranty.

Breathe Ability (4): Breathable, yet water resistant. Surlast is lighter than Sunbrella, but the urethane coating adds increased water resistance.

Waterproof (3): The urethane coating adds water resistance, but the fabric can still breathe and therefore is not waterproof.

Abrasion Resistance (5): Polyester fabric is inherently more abrasion resistant than acrylic fabrics like Sunbrella making SurLast ideal for trailer boat covers where the fabric moves and flaps a lot. Soft, tightly woven construction is very kind to gelcoat and painted surfaces.

UV Resistance (3): Polyester is a UV resistant material but less so than acrylic fabrics like Sunbrella or vinyl coated polyester fabrics like Stamoid.

Colorfastness (5): Solution dyed means that the yarn color runs throughout the cross-section of the fiber and equates to excellent colorfastness.

Clean ability (4): Easy to clean, and although a soft tight weave, dirt easily washes free from the crevasses of the yarn. The urethane coating on one side does make dislodging dirt slightly more difficult than cleaning non-coated woven fabrics.
