Leveraging the advanced fabric technology of Nucliex STR 180 Merino wool, the Satoro AR Boxer is a comfortable, odour resistant mens baselayer designed for prolonged backcountry use and all round wear. Each Nucliex yarn is created by wrapping Merino fibres around a nylon filament to combine the natural softness, efficiency and odour resistance of wool with the durability of the nylon core. Merrow and flatlock stitched seams minimize irritation.
