Milliken Sand/Tan Polyester ECWCS Gen 3 Level 1 Base Layer Bottoms - New
The USGI
Milliken Sand/Tan Polyester ECWCS Gen 3 Level 1 Base Layer Bottoms (Silkweight
Drawers) are mission-essential thermal utility underwear engineered for the
United States Armed Forces as part of the Generation III Extended Cold Weather
Clothing System (ECWCS). Designed to serve as the foundational
moisture-management layer worn next to skin, these silkweight bottoms actively
draw perspiration away from the body during high-exertion tactical maneuvers to
prevent cold-weather heat loss and keep the operator dry, warm, and comfortable
in harsh environments.
Constructed
from advanced 100% Milliken polyester grid-knit performance fabric, this
base layer combines ultralight structural weight with high thermal efficiency
and rapid drying speeds. The Sand/Tan color profile integrates seamlessly under
duty uniforms, flight suits, or combat trousers. Engineered for active
movement, these drawers feature smooth flatlock seams to completely eliminate
friction chafing under heavy gear, an elastic waistband for a contoured fit,
and an accessible fly opening for field utility.
Arriving in Brand
New / Unissued (New Old Stock) condition, these thermal bottoms are
pristine military surplus. They retain their original factory-fresh fabric
elasticity, crisp defense labeling, unfrayed flatlock stitching, and clean,
uniform sand/tan coloration.
