USMC Digital Camo, Poncho Liner - A Remarkable Piece of Technology.

The USMC poncho liner was originally designed for warm weather use. The great thing about the poncho liner is that for camping or summer sleeping it beats a light blanket or sleeping bag. One poncho liner in a tent on a warm summer's night is all that's necessary for comfort. When a sleeping bag is too much and a sheet is too little, the poncho liner is just right. So instead of a bulky sleeping bag that takes up tons of room, use a poncho liner instead.
