USGI ECWCS Generation III Mid Weight Pants

These are genuine USGI ECWCS Generation III Level 2 Mid Weight Pants, the issued cold-weather base layer worn by U.S. soldiers across every branch. Built from a breathable polyester/spandex grid fleece, they trap warmth in low-loft pockets while wicking sweat away and venting excess heat during movement. As Level 2 in the seven-level Extreme Cold Weather Clothing System, they function as a standalone insulating layer in the 30°F to 50°F range or as the foundation for heavier layering when temperatures drop. Anti-microbial treatment, flatlock seams, and elastic waist and cuffs make them a workhorse for field use, hunting, winter training, and cold-weather operations.

Description

Features

  1. Genuine USGI Issue — Authentic U.S. military-contracted ECWCS Generation III Level 2 base layer bottoms, RFI-issued to deployed service members.
  2. Mid-Weight Grid Fleece Construction — Polyester/spandex grid fleece traps body heat in low-loft pockets while allowing air to move, preventing overheating during activity.
  3. Level 2 in the ECWCS System — Designed to be worn as a standalone base layer or over Level 1 silkweight bottoms, with Levels 3 through 7 layered on top as conditions demand.
  4. Moisture-Wicking Performance — Pulls sweat off the skin and disperses it through the fabric, keeping you dry during cold-weather movement, patrols, or field work.
  5. Anti-Microbial Treatment — Built-in odor control allows for extended wear in the field between washes.
  6. Elastic Waistband and Cuffs — Stretch waist and ankle cuffs keep the pants in position under trousers without bunching or riding up.
  7. Four-Way Stretch Fabric — Spandex content allows full range of motion for running, climbing, and squatting under load.
  8. Flatlock Stitched Seams — Low-profile seams lay flat against the skin to prevent chafing under combat trousers or hardshells.
  9. Operating Temperature Range — Engineered for service in the 30°F to 50°F band, with broader range when paired with additional ECWCS layers.
  10. Tan 499 Colorway — Standard military-issue tan 499, designed to remain invisible under ACU and OCP uniforms.
