Each cam in the Wild Country Helium Friend with Extendable Sling Set comes from decades of research and whipping while trad climbing. Modern updates include a superlight hot forged construction, a longer stem for easier placements in shallow cracks, a smoother trigger with secure stops, and an extendable Dyneema sling so you can leave the runners at home. Helium Friends come with the original single stem, single axle design with a 13. 75 degree camming angle. There are full strength cam stops that permit passive placements.
