If you want the best of the best, we made this for you. A 7075 aluminum crampon body is just as strong, but lighter and thinner than our standard Ibex. It slices through the snow even better with less drag, saving you valuable energy output on the skintrack. The dual-width design features one crampon that is slightly wider than the other, allowing the crampons to nest together for easy handling and reduced packing space. All in all, the Ibex Pro crampon is 22% lighter than our standard Ibex - the lightest split crampon in the world!
