The Primary Arms Shooting Mat, Flat Dark Earth, is waterproof and features an anti-bacterial coating. A thick padding area keeps you comfortable and stake-down grommets on each corner keep it from flying away (bring your own stakes). It unfolds to a generous 72 inches long by 30 inches wide, and then rolls up to about a 4 inch by 8 inch roll, held together by a pair of plastic cross buckles. This tough shooting mat features a 1-year warranty.
