Protection from heat and UV rays - Never doubt the power of our sun. Leave your board in the sun to bake and that beautiful board of yours will sizzle like unprotected skin.  The VAMO UV cover is made with UV protectant fabric designed to keep your board 30 degrees cooler when sitting in direct sunlight. In direct sunlight the dark colors on your board can reach uprights of 150 degrees, which is well past the epoxy and EPS melt rate of 130 degrees. Prolonged heat exposure will lead to delimitation, oxidization, melting epoxy, or seam leaks on inflatables. That's the long way of saying, let VAMO soak up the suns harmful rays not your beautiful board. For boards 10'6 up to 12'
