Lyman's whole line of shooting bags help to create a stable shooting platform in almost any situation. The shooting bags are made from heavy duty, abrasion resistant 600D nylon with micro-suede padding on rifle contact points. They are also equipped with a non-slip rubberized base to keep them stable and in place during use. The bags are supplied filled with a ground plastic material which holds its shape well and is light enough for easy carrying. Filling can be adjusted for optimal volume.
