A mask strap is an affordable but invaluable accessory for your dive gear. New masks usually come equipped with a silicone mask strap that will cause damage to your hair. When it comes to replacing the silicone strap, the best option is neoprene with nylon straps. This system provides the most hair protection as others only cover parts of the silicone strap or use Velcro and still damage your hair. Our mask straps distribute pressure equally across the back of your head to keep the mask straight and to apply equal tension on the skirt for a much better seal.
