A surf leash should match the length of your board and the power of the waves you plan to ride. For everyday conditions, choose a leash at least as long as the board so there is room between you and the board after a fall. A longboard generally needs a longer leash than a shortboard, while more powerful surf may call for a stronger cord. Check the product details for cord thickness, cuff construction, rail saver, swivel hardware, and intended use. A lighter competition-style leash can reduce drag in smaller surf, but an everyday leash may be the better choice when durability matters more. Inspect the cord, swivel, cuff, and rail saver before every session, and replace a leash that shows cuts, stiffness, fraying, or damaged hardware. No leash removes the need to control your board and keep distance from other surfers. Match your leash with your surfboard, then add wax from the Surf Wax collection.
