The highly versatile Mammut Ophir 4 Slide Harness brings the comfort without the weight for trad, sport, gym, and multi-pitch routes. The two-part webbing technology minimizes pressure points without adding extra padding to create a lighter, more comfortable harness by boosting airflow and mobility, so we feel free on the wall. To find our perfect fit over the day's layers, we simply cinch the 4 quick-fit buckles that keep the belay loop and waist belt centered.
