High-tech bandages for optimal protection. Our primary goal of Impact Bandages is to protect your hands. Especially with frequent training on the sandbag, the knuckles often suffer. This can result in long-lasting, painful injuries. To prevent this, we use an approx. 1cm thick gel layer that protects your ankles perfectly from the impact. In order to protect not only the knuckles but also the wrist, the Impact Gel bandages have a long bandage that is wrapped around the wrist.
