Koola Bucks Antimicrobial Game Bags are proven in certified laboratories to reduce the growth of surface bacteria by 8X the amount of standard game bags. The bags are made from a tightly knitted blend of cotton/poly material designed for strength and durability in the field. They are treated with a proprietary blend of all natural falvorless products that include lactic and citric acids derived from fruits. Lactic and citric acids are diluted to levels that pose no potential health risk and product has been approved for food grade applications. When meat is placed inside the bag the inhibitors contact and transfer to meat reducing the growth of surface bacteria, allowing you to age your meat much longer with less waste and surface spoilage. The bags repel egg laying insects, hold moisture, keep dust off, and provide added protection during warm weather.
