The COT-tech creates slightly shorter skis but leaves no compromises around usability. The effective edge extends nearly the entire length of the ski. If backcountry agility is your thing and you're used to skiing 180-185 cm touring skis, for the Supernova we recommend the 177 cm length. No need to carry the extra weight, while the extra length would only get in your way on switchbacks. The COT design was developed to let you comfortably and safely use shorter and lighter skis with the confidence of a bigger and heavier ski. With the COT design, you're more agile on the skin track and are able to reach your goals faster. You also get much more versatile and yet stable, light, carbon skis for gnarly, steep and tight terrain such as narrow couloirs and tree runs. The Supernova Carbon topsheet features bright gray color spiced with a metallic finish that creates stunning looking skis.
