Hyperwear makes the best weight vest for men and women. Working out with a weight vest when training for running, Crossfit, obstacle races like Spartan Race, Tough Mudder or sports like football, basketball or soccer will get you more results in less time. Walking with a weight vest for osteoporosis is proven to build bone density. The Hyper Vest is the thinnest weighed vest made with a patented control system that holds weight comfortably to your body without bouncing while still allowing you to expand your chest for breathing. The unique side-cords can be adjusted to keep the weight tight to your core and not hanging on your shoulders. Only our durable weight vests have steel weights that are denser and thinner than any other weighted vest.
