The Cavemaster seat harness uses coated webbing, which provides the best wear and abrasion resistance of any cave harness on the market today. Its low attachment point works well with Frog Climbing Systems. Unlike other models, CMI uses three webbing gear loops rather than metal D-rings so the gear loops lay flat and do not catch on rocks. Cinch buckles on the outsides of the legs and back ensure there are no pinch points. This harness closes uses a Maillon-Rapide Half-Moon Screwlink. This harness is simple, effective and wears like iron! One size fits waists up to 42 inches; it weighs 1.45 pounds.
