You can never have too many Nanos. Especially if you’re the type to litter the mountain with biners. The 22 is a revamped version of the classic CAMP Nano carabiner, which set the standard for lightweight functionality. The new version has a refined gate for easier clipping and a deeper basket for holding the rope position. CAMP also managed to increase the open-gate strength while subtracting a gram. The biggest little biner on the market comes in eight colors for your sorting and racking pleasure.
