The Original Long Sleeve Half zip is one of our 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. Half zip for temperature regulation. Merino gives you extra protection against the sun's harmful rays, naturally. Merino absorbs and releases vapour to prevent overheating and clamminess. Naturally anti-bacterial, it can be worn for days without washing. Merino naturally keeps you warm in cold weather and cool in warm weather.
