3kg - Seventh Sin Slam Ball
Seventh Sin Slam Balls are designed to take the abuse from even the most aggressive of users and come back for more. Made from an ultra-durable textured rubber shell, they offer great grip even when you're dripping in sweat. We use a very fine sand as the filler to provide optimal fluidity of movement.
It's time for you to get the benefit of a full body work out, courtesy of Seventh Sin.
