The PKS Smart Cuff is a purpose built Wrist cuff for wingboarding that has two different "locking" features. The first is a low profile "tounge" that keeps the velcro closure flat and even help to prevent anything getting under it and opening the wrist leash. The second is an over lock velcro closure that closes across the main velcro strap to prevent the wrist cuff strap from inadvertantly being opened.
