When it comes to putting your life on the line, it pays to have the right equipment. Cams are brilliantly engineered devices that climbers can wedge into cracks on rock faces to use as anchor points. If they fall, the climber’s weight creates tension on the rope and causes the cam to expand in the crack. These Dragon cams by DMM are lightweight and rated to a minimum passive strength of nine kilonewtons. Plus, though it may not be the first thing that passes through a plummeting climber’s mind, they are also beautifully designed.
