Original Scent Shield was the first scent elimination product on the market for the hunter and remains America's best-selling formula. Scent Shield's exclusive scent eliminating properties interfere with the natural creation of odor at the molecular level by stopping odors from forming into a gas. No gas, no odor. It worked then and it works even better now with the addition of the powerful bacteriostat, Pro Power2. Pro Power2 attacks skin borne bacteria that cause human odor. Control bacteria that cause odor and you control odor. Scent Shield with Pro Power2 is the only dual ingredient formula that controls human odor by attacking it at both the molecular and bacterial level. It remains the strongest, most effective non-carbon odor fighter available today. It is designed for use on boots, outer and under garments as well as for use on hunting equipment-treestands, arrows, wrist straps and any other item capable of holding and dispersing a scent. 24 oz. Combo Spray Bottle. Scent Shield
