Bandages and various straps (supports) are primarily designed to protect bones and joints from impact in contact sports or when training on bags. If someone has poor punching technique, they provide excellent support to the wrist and arm in a way that ensures a level position of the arm, thereby reducing stress on the wrong part of the arm or hand. This reduces the risk of injuries, and hand injuries most commonly occur in boxers, i.e., in contact sports. They are available in different lengths, elastic or non-elastic, and made from various materials.
