Since their introduction in 2005 the Stretch-Air Climbing Trousers have been the first choice for competition tree climbers throughout the world. Durable, functional and comfortable these specially designed close-fit pants have a preformed knee for extra comfort. The knee patch and lower inside leg are made from Kevlar to ensure longevity. The zipped leg opening has a debris catcher to keep unwanted dirt from entering your boots. The pockets are located for easy opening while wearing your harness, and the legs are long enough so they won't ride up while climbing. Patented 4-way stretch elastic outer fabric which allows for easy movement in the tree. Two side pockets (zipper closes down) and one large Velcro leg pocket - also has a secure easy-access pocket for your phone.
