USGI Bear Suit Overalls

The USGI Bear Suit overalls are a component of the Extended Cold Weather Clothing System – they are not a pair of overalls designed for a wild brown bear. In fact, I can guarantee your unhappiness if you attempt to put them on said animal. Instead, consider picking up a pair for cold weather work, hunting, snowboarding or any other winter activity.

Each pair of USGI Bear Suit overalls offered by is an authentic United States Military surplus item. As such, each pair of these overalls, known officially as a bib, was originally designed by Tennier Industries, Inc. and issued to members of the U.S. Military, including those serving in the Marines, the Special Forces, the Army and the Air Force.

Though we are unable to confirm issuance of our USGI Bear Suit overalls, each pair appears to remain in excellent to like-new condition, and is still fully capable of providing prospective buyers with years of service stateside. Likewise, these cold-weather overalls are free from the typical rips, tears, stains and scents that often plague previously issued military surplus clothing. Those looking for a unique piece of American Military history or a warm layer to protect against harsh outdoor elements are sure to love the USGI Bear Suit overall.

Interesting is the fact that the USGI Bear Suit overalls are a singular component of the first generation of the Extended Cold Weather Clothing System, or ECWCS. The ECWCS is a protective clothing system that was originally developed by the U.S. Army Natick Soldier Research, Development and Engineering Center during the 1980s as a means to provide protection to U.S. soldiers from a range of extreme combat environments. The first generation of the ECWCS consists of a Gore-Tex® parka and trousers alongside 20 other pieces of individual clothing, including the USGI Bear Suit overalls.

The USGI Bear Suit overalls are part of the second layer of the first generation of the ECWCS, and serve as a layer of insulation between the base and outer layers of the system. As such, these overalls are designed to fit snugly, as they were meant to be worn underneath an outer layer. Nevertheless, these warm overalls, which are constructed entirely from polyester fiber-pile, are sure to serve some purpose. They are relatively featureless, though they do include elastic overalls with quick-release plastic buckles as well as full-length side zipper and a zipper through the seat.

Prospective buyers may also be interested to learn the NATO Stock Number (NSN) for the USGI Bear Suit overalls, which is printed on the manufacturer tag. An NSN is a 13-digit numerical code that identifies all standardized materials of supply that are recognized by NATO countries. The NSN for the M2HB back plate assembly is 8415-01-228-1328, which officially identifies the item as cold weather bib overalls. The "8415" corresponds to the item's NATO Supply Classification Group (NSCG), and identifies it as a piece of special purpose clothing, while the "01" corresponds to the item's National Codification Bureau (NCB) code, or country code, and signifies that the piece is from the United States. The remaining digits signify its item number.

A lot of bang for the buck here - zipper legs, zipper front & back crotch, poly-fleece lined
I'm 6'2" and the large (short) seems fine with plenty of room
.... again, I think it's a lot of bang for the buck here ......
