Chammyz The Aussie Sweater viscose 100% viscose. Whether you are a surfer, lifeguard or diver who is repeatedly getting in and out of the water, you can depend on Chammyz providing a continuously dry garment. Unlike cotton that will retain moisture, Chammyz will absorb (wick) the water away from the body, and then start an evaporation process immediately. Tapered cut with collared neck creates a streamline fit for everyday wear. Machine Wash Cold, Tumble Dry low, No Bleach, Be Kind to All Animals, People and The Earth Canada
