Dead Down Wind's ScentPrevent bio-engineered scent elimination incorporates powerful nanozyme technology, which uses an enzyme to target bacteria - the source of human odor. Rather than masking scent, it actually prevents odor-causing bacteria from forming, allowing you to hunt in a zero-scent environment. ScentPrevent products are enzymatically performance grouped to help you develop your own scent elimination approach. Add Dead Down Wind ScentPrevent Dryer Sheets to your dryer load to remove all trace of human scent from your hunting clothes. Pair with ScentPrevent Laundry Detergent for the most effective odor elimination (not included).
