NOS! This means "new old stock", which in turn means these wonderful things are unused – not everyday you come by such classic military items in almost pristine condition! So, this here is called a Woobie, because "without one, you woobie cold!" A very nice light blanket that has more uses than you'd think thanks to the tie strings everywhere.
Originally used in the Vietnam War, this lightweight rain poncho liner was meant as a replacement for the wool blanket and tied up with the rain poncho to make a light sleeping bag. Compared to the blanket, this is a lot lighter, a bit warmer dries faster, and can be packed into a very small space. Not only praised by Vietnam War veterans but veterans of more modern conflicts as well - this thing is still very much in use.
If you want to read more praise and interesting bits of info, head over to Task & Purpose, and read their educational and entertaining article.
Genuine US surplus
Condition is NOS, unissued. There are no signs of use, and the fabric colors have only seen the test of storage time.
