HAAS Tree Ascender System

This revolutionary system allows for quick, easy ascents! The HAAS’s fully integrated knee ascender captures 100% of the advancement made by a traditional foot ascender worn on your opposite side. The bungee design runs the length of the lower tether to provide full operational range of pull for faster, better coordinated climbing. More ergonomic than foot locking, the HAAS features an adjustable foot loop and can be used in single rope or double rope systems. Works with ropes up to 1/2” in diameter. Traditional foot ascender not included.
