The Metolius Master Cam is a flexible, single-stem unit with an optimised cam angle for increased holding power when rock climbing. The new Ultralight Master Cams are twenty percent lighter than the originals. If you carry a double set of cams, the weight savings is the same as a twelve ounce canned beverage of your choice. When compared to other brands, the weight savings can be much more. The new shark fin tooth pattern gives optimised bite in soft rock.
