The Ophir collection consists of Mammut's more versatile harnesses for all-round climbing on rock or ice, and the Ophir Fast Adjust Harness is the quickest option to put on and take off. The Fast Adjust leg loops slide quickly and stay securely fastened throughout your climb, and the waist buckle self-locks for reliable security. It still sports Mammut's two-part construction for reduced weight and solid support, and the tie-in loop has Mammut's abrasion protector for increased durability. Mammut also reinforced the haul loop with an extraordinarily strong 4kN rating.
