Made of highly durable natural rubber, these fins deliver high performance for all kinds of kicks. The high-density rubber also makes them negatively buoyant—a highly desirable feature when using a dry suit and a tech rig with a steel plate. Features a patented bungee strap that offers great comfort and makes donning and doffing simple and a full-shape foot pocket.
