Dead Down Wind is an all-new odor-prevention system that uses a revolutionary, patented bio-engineering process known as Enzyme Scent Prevention. This innovative new technology contains a strand of enzymes that target human bacteria - the source of game-spooking odor. Unlike cover sprays, Dead Down Wind prevents odor-causing bacteria from forming, so you can be confident you're hunting in a zero-scent environment. The ScentPrevent Laundry Detergent eliminates all human odors in clothing and prevents their recurrence. UV inhibitors prevent camo from fading. Carbon-suit friendly. 32-oz. bottle.
