The Blue Ice Choucas Harness boasts an ultralight design-just 84 grams-making it the lightest harness on the market. The compact, superlight materials allow the Choucas to be rolled up to about the size of a fist, so it can be easily stashed away during fast-and-light mountaineering and ski mountaineering objectives. One of our favorite features on the Choucas, however, are the independent leg loops that can be opened up for easy on and off while wearing crampons.
