Technical alpine pants don't get more technical than the Helly Hansen Men's Odin Mountain Pant. Full stretch HellyTech Professional construction ensures dryness and breathability for high output pursuits. These pants were field tested in extreme conditions from the Himalayas to the Antarctic Ocean, and you can tell when you take these suckers out to the tundra. The welded KEVLAR kick panels protect the inner legs from crampons and ski edges. This pant has 34 Length YKK Aquaguard side zips, which provide emergency ventilation and snag free dressing over boots. YKK Aquaguard zippers at the chest, hand, and thigh pockets, plus an Aquaguard zipper at the fly, make sure water stays on the outside.
