Have peace of mind knowing your boat is safe with these non-fade trailerable boat covers. When designing these boat covers, we sourced samples from fabric suppliers and put them through independent testing. The clear winner was an exclusive 600D canvas that's breathable and water-repellent with excellent tear resistance in both directions. But we didn't stop there. The nylon loops and stitching were also put through stress testing to ensure they will not fail during trailering.
