Sunbrella SeaMark Charcoal Grey 2110-0063 is a 60-inch wide marine and awning fabric that combines durable solution-dyed acrylic with a textured, color-matched vinyl backing to deliver full waterproof protection. Designed for boat covers, awnings, canopies, T-tops, and outdoor upholstery, this heavyweight woven fabric is resistant to mildew, UV damage, fading, abrasion, and cracking. Its fluorocarbon finish on top and marine-grade vinyl coating on the back ensure long-lasting performance in harsh outdoor conditions. Easy to clean and heat-sealable, it is available in 50-yard rolls and backed by a 5-year warranty. Note that its weight makes it unsuitable for retractable awnings.
