Tree climbing harnesses are among the most important elements in a climbing system. Tree climbers are connected to the system through the harness, and it protects them from falling. In addition, they often move around in the harness through the whole day. Functionality, quality and comfort are more important for a tree climbing harness in professional tree care than for any other element of the personal protective equipment (PPE) and the tree climbing equipment. All these aspects ensure that tree climbers can work effectively and gently on their bodies.
