The Boardskin is a thin reflective sheath for your board it will protect it from the sun and has the advantage over a sock of not allowing water to soak in making it even better for protecting your car from the sand and water from your board. There is no padding in the boardskin if you want to protect the board from knocks we'd recommend at least a 5mm board bag. :: Unisex > Boardbags Size: 7FT 6,7FT 0.
