For a cool fit and optimal comfort, the Agner hemp tank top is made from our exclusive Alpine Hemp fabric, a blend of alpine hemp (70% cotton, 30% hemp) for natural odour-resistance and easy maintenance. Hemp may feel soft to the touch, but it is the most durable natural fibre known to mankind. It features additional Durastretch fabric inserts on the shoulders for better protection and enhanced abrasion resistance when wearing a backpack. Round neck.
