Dry Wolf Training Tank True to Size Microfiber Polyester Cold Wash | Hang Dry Recommended Dry Wolf polyester fabric designed to help keep you dry so you can more comfortably work harder, longer. Dry Wolf's unique high-performance microfiber construction supports the body's natural cooling system by wicking away sweat and dispersing it evenly throughout the surface of the garment so that it evaporates quickly. Dry Wolf clothes are most effective as a base layer or on their own. Direct contact with your body means you stay dryer. Dry Wolf sweat-managing properties are permanent for the life of the clothing.
