US Military Extreme Cold Weather Trousers Gen III

Gen III Cold Weather Pants

These are the insulated trousers from the US Army's Gen III Extreme Cold Weather Clothing System (ECWCS), the layered cold weather kit issued to American troops. They fill in at the warmest end of that system, going on over base layers when you stop moving in freezing temperatures. Hunters, winter campers and anyone who works outside in deep cold use them as a warm outer layer or as insulation under a shell.

Features

• PrimaLoft Insulation — PrimaLoft is a synthetic insulation that traps warmth like down but keeps more of its warmth when it gets damp.
• Compressible Fill — The synthetic fill packs down small, so the trousers fit in a ruck or vehicle bag until the temperature drops.
• Elasticated Waistband — A fully elastic waist pulls on easily over other layers and holds without a belt.
• Front Fly Closure — A covered front fly gives you access without dropping the trousers in the cold.
• Articulated Knees — Shaped, seamed knee panels let your legs bend freely when kneeling, climbing or crouching.
• Elastic Ankle Cuffs — Gathered cuffs at the hem seal out drafts and sit neatly over or inside boots.
• Gray Colorway — The flat gray shell matches the rest of the Gen III ECWCS insulation layers.
• Layering-System Design — Cut roomy to go over base and mid layers, in line with the ECWCS approach of adding or removing pieces as conditions change.

US Army ECWCS Issue

This is genuine US Army issue, made to the military's specification for the Gen III ECWCS rather than a commercial copy of it. The pattern pairs a lightweight shell with PrimaLoft fill and keeps the details simple: elastic at the waist and ankles, articulated knees and a front fly. If you are building a full ECWCS set, or just want military-spec cold weather insulation for the field, these are the trousers that went with it.
