A surfboard cover may cover the bottom and side rails of a surfboard. The cover may leave about 90% of the surfboard's top exposed. The cover may include an elastic and/or a drawstring so that the cover may be placed on the surfboard. A cut out may be disposed on the cover to accommodate a fin to slip through. The cover may reduce or eliminate wax build-up from inside the cover, may protect the board when, for example, the board is placed on the ground while waxing the top side.
