The SPARTAN by Weis Running Belt was designed by a team of athletes, adventurers and long distance runners who understand that details can make or break a race, a workout or a long run.  The running belt was crafted with a minimalist plan in mind, with enormous freedom of movement and easy access to stored objects. Empty it is ultra-thin, with the capacity to triple its storage capacity. The elastic strap adjusts to the body and reduces rebound impact.
