The evolution of the Nano continues. Following the popular Nano Wire and Nano 23, the new Nano 22 is even lighter, stronger, and more functional. The Nano 22 features a completely new design with a stronger open gate strength, 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. Like an inner working space large enough to use a clove hitch with ropes of any diameter, a gate opening wide enough for easy clipping on the sharp end, and a profiled nose that slips in and out of tight chain links. As the trend towards lighter and faster, bigger and bolder continues, the Nano continues to set the standard for carabiners in the area of lightweight functionality. The Nano 22 rack pack includes on of each color nano, made to coordinate with the colors of your cams for faster gear selection and placement.
