Ergodyne - EGO42320 6491 Reversible Thermal Multi-Band is the ultimate defense against cold, wind, snow, sun and dust. Interior, soft fleece provides warmth and comfort in cold temperatures. Exterior, moisture-wicking polyester dries fast and absorbs sweat for all-day wear. Reverse the double-sided, multi-band based to your preference. Stay warm on a frigid day or stay covered and dry on a cool day. Material stretches to fit comfortably and accommodates a variety of head sizes. Wear it as a neck gaiter, face mask, head covering, hat, dew rag and other protection. Machine-wash the multi-band to wear the next day.
