The evolution of the Nano continues. Following the popular Nano Wire and Nano 23, the Nano 22 is even lighter, stronger, and more functional. The Nano 22 features a special design that is 1 kN stronger in all three of the strength ratings, a deeper basket for holding the rope in its proper position, and a refined gate for smooth, easy clipping. At 22 grams, the Nano 22 is the lightest fully-functional carabiner on the market with unique attributes that set it apart from other smaller carabiners.
