Precursor to the modern ECWS system, the USGI "Bear Suit" was a set comprised of a pair of synthetic pile pants and a jacket. Maligned as bulky by some, these pants are a blunt answer to brutally cold conditions. 

Designed to be worn below more water-resistant layers, these feature two full-length zippers down the sides, a fly, and a set of suspenders. 

Features: 

• Zip-up fly and side zippers
• Set of elastic suspenders
• Warm when wet, synthetic pile material
• Authentic USGI surplus
