Hyperwear is a sports & fitness company dedicated to the development of unconventional tools for unconventional training. Traditional metal weights are rigid and will cause damage & injury when used with too much speed, so they invented the SandBell. Drop it, throw it, slam it; it will withstand even your toughest workout. Other weights vests are clunky & inflexible, slowing you down at every turn. So they invented the Hyper Vest, a weight vest designed to move with you so you can push your limits & reach your goals.
