The new Fast Adjust adjustment system allows you to adjust the width of the leg loops within seconds: simply slide the Fast Adjust buckle along the load-bearing webbing until the harness fits perfectly. This novel adjustment system solves the tiresome problem of ends of webbing that stick out and get in the way. Thanks to the Mammut two-part webbing technology, the Ophir Fast Adjust also offers optimal comfort, extremely high breathability and maximum freedom of movement for climbing in the gym, out on the rocks or in alpine terrain.
