Military Underwear and Base Layer Apparel

Anchortex Corporation provides a variety of base layer undergarments to meet specific needs for flame resistance, moisture wicking, heat retention, and other military specifications as the situation demands. Our undergarments are used to supply reserves and recruits in training as well as personnel on active duty on base and in forward deployment zones. These major brand base layer items are often used as commercial substitutes for ECWCS level 1 and ECWCS level 2 garments.

The Extended Climate Warfighter Clothing System, or Gen III ECWCS, is protective clothing created in the 1980s as an exclusively cold weather system by the United States Army Natick Soldier Research, Development and Engineering Center, Natick, Massachusetts, but has been radically redesigned to cover a broad range of combat climates. The first generation ECWCS (Extended Cold Weather Clothing System) consisted of parka and trousers plus 20 other individual clothing, handwear, headwear and footwear items which are used in various combinations to meet the cold weather environmental requirements of the US military (and others). Now, the third generation, or Gen III ECWCS, has been developed to maintain adequate environmental protection in temperatures ranging between +40° and −60° Fahrenheit (+4° and -51° Celsius).

The complete system features seven levels of protection to provide defense from environmental conditions. All garments are designed to enhance a soldier's ability to train and operate in many combat conditions.

Levels of Protection

Level I: Light-Weight Undershirt & Drawers
Level II: Mid-Weight Shirt & Drawers
Level III: High-Loft Fleece Jacket
Level IV: Wind Jacket
Level V: Soft Shell Cold Weather Jacket & Trousers
Level VI: Extreme Wet/Cold Weather Jacket & Trousers
Level VII: Extreme Cold Weather Parka & Trousers
