This uniquely designed medicine ball is one of a kind. We used tire technology to combine the best natural rubber with DuPont™ Kevlar® fiber making this the most durable medicine ball on the market. This is truly an evolution in a product that hasn’t seen progress in decades. Unique custom pattern provides grippy texture to aid in catching, throwing, slamming, or moving with the ball in general. This ball has a medium bounce to it and is not a dead bounce slam ball.
