PROTECT YOUR SUP - The sun's UV rays can cause your SUP to discolor, and even cause the fiberglass to deteriorate and flake off (see what happened to Stevie's paddle board in the picture). Covering your expensive Paddleboard with this sock will protect it from sun damage. The sock cover also protects your SUP board from dings and scratches while loading it onto the top of your vehicle, or storing it inside/outside between paddle sessions. COVERS ALL SIZES OF STAND UP PADDLEBOARDS - Our stretchy knit plush polyester SUP Socks are extra-wide, to fit any paddle board. 8'0" SUP Sock is 30" wide when unstretched. 9'0" SUP Sock is 32" wide when unstretched. 10'0", 11'0", and 12'0" SUP Socks are 34" wide when unstretched. FOR HARDBOARDS or INFLATABLE PADDLEBOARD (iSUP) - Our sock cover protects all kinds of SUPs, whether you have a classic hard paddleboard or the newer inflatable paddleboard. You don't need to remove your fin(s), just tighten the drawstring around the tail end of your board, and you're good to go. REINFORCED PADDED ROUND NOSE keeps your SUP's nose well protected with 600D Nylon on top of the knit polyester. There's a velcro pocket at the tail end for snacks, wax, or other goodies. And you can roll up your sock nice and compactly, store it in the included mesh bag, and toss it in your vehicle for safe storage while you are out paddling.
