The Arctic is low in bulk yet offers two layers of thermal protection. The undergarment’s wicking ability pulls perspiration and even minor water leakage away from bare skin for greater comfort and warmth. The two-piece design has good overlap to create a seamless wrap of thermal protection. It’s machine washable for added convenience, and available in 11 mens and 11 womens sizes.
