Wearing a leash in combination with a belt around the waist is preferred by many today. It is comfortable and does not restrict freedom of movement. In fast-flowing waters, a leash with a belt should definitely be chosen. If the leash gets tangled on obstacles, the current can pull a stand-up paddler down. The quick-release function on the belt allows the paddler to quickly separate from the leash and thus from the board. The °hf Synergy belt is also equipped with the RESTUBE READY interface, which is used to attach a restube. Should you need to separate from the board, Restube gives you extra buoyancy and visibility.
