The perfect pant for those who have shell pants or bibs. On some of the coldest days of these season, The Helly Hansen Lifaloft Full-Zip 3/4 pant is exactly what you need. It gives you all of the extra warmth you need on your thighs, knees, and upper calves. With this being a 3/4 pant, you do not have to worry about it bunching above your ski boots. We love these pants because they help you stay out longer on the coldest of days.
