Where others see limits, we see opportunities. Traditional metal weights are rigid and will cause damage & injury when used with too much speed, so we invented the SandBell®. Drop it, throw it, slam it; it will withstand even your toughest workout. Other weight vests are clunky & inflexible, slowing you down at every turn.The Hyper Vest PRO® is designed to move with you so you can push your limits & reach your goals. We don’t exist in a static environment, so neither should our training. #TRAINHYPERWEAR to build strength, mobility, stability, agility, speed and power so you can perform at your best.
