The Level Six SUP Sock is a lightweight extra stretchy sock to protect your SUP from dings, sun exposure and more. We also include a tie down point on the nose so you can securely tie it down to your vehicle for long hauls. This SUP sock is sized for a sock-like fit on most boards. Packs down much smaller then a traditional SUP Board bag and comes in a compact mesh carrying bag. They can accommodate almost any width as they are extra stretchy if you are purchasing one for a non Level Six brand board.
