up for a Buy Now Auction is a US Military Issue Cold Weather Pile Cap communally called a helmet liner. This is a warm cold weather winter hat. That would be issued to US Soldiers during the winter. The hat is Woodland Camo in color . The hat is made from cotton and has a wool lining. The hat has a bill that folds up. The hat is US Military Surplus. I am listing it as used but it is in good usable condition. To me it looks new old stock. I have 10 of these hats in the warehouse so the tag inside my be different but the hats size is 7 1/4
