Avery LayOut Mat was designed by Avery pro-staffers who had spent one too many mornings on wet ground waiting for ducks and geese to decoy! This "must-have" mat is made from urethane coated 600-denier polyester backed with heavy-duty PVC so that no water leaks through. Simply roll up and fasten when not in use. Shoulder strap allows simple transportation to and from the field. Killer Weed camouflage.
