The Icebreaker Men's Original Long Sleeve Half Zip is one of Icebreaker's earliest designs, and has developed an iconic status as one of the most versatile sweaters a guy can own. This timeless classic is made from 320gm pure merino Jersey, a very soft, breathable, warm fabric that resists pilling, fights odor naturally, and looks great in every environment. The Original Long Sleeve Half Zip makes a great midlayer for skiing, a warm but breathable top for hikes in cool to cold weather, or a refined top for adventures in the city.
