It’s undisputed that if a soldier would go in the wilderness for an extended period of time, one of the few things he’d take along would be the woobie. The beautiful polyester camo encased in two layers of joyous quilted nylon is a universal staple for the infantryman.

If you search online for the term woobie, you’ll get various results, from poncho liner to sleeping bags, to blankets, to baby blankets, and yes, even hoodies now.

Woobie is also used as a term of great affection. Calling someone a “woobie” is basically the same as calling them “love” or “sweaty.”

But when it comes to the military, the woobie is the nickname given to the poncho liner issued to all soldiers. The woobie is not a new thing with the first used in the jungles of Vietnam.


A Term of Uncertain Origins

How the term “woobie” came to be applied to the poncho liner remains a mystery. Some claim that it started as the phrase, “Because you would be cold without it” and “would be” evolved into “woobie.” Or that it was called a “willbie” from the phrase, “It will be what keeps you from freezing.”

Now anyone has access to woobies. They are sold online and now come in various fabrics, prints, colors, prices, and qualities. Woobies have been widely advertised to civilians. Hunters and campers use them during cold and wet weather. Picnickers and stadium goers use them as blankets. People even use them as comforters and couch blankets at home.

I use mine as a pillow on a hot summer afternoon and always place it inside my ruck frame to give me a little padding on my back and allow me to quickly access it.
