Teesar US Thermo Fleece Underwear Set GEN III Level II – Advanced Cold-Weather Base Layer

Conquer freezing environments with the Teesar US Thermo Fleece Underwear Set GEN III Level II. Developed as part of the advanced Extended Cold Weather Clothing System (ECWCS), this functional two-piece set (comprising a long-sleeve thermo undershirt and thermo long johns) acts as a high-efficiency thermal barrier against low temperatures.

Engineered from a premium blend of 95% polyester and 5% elastane, the fabric features an ultra-elastic netting construction that grants unrestricted room to move. The interior is lined with a specialized comb-fleece structure: its micro-channels trap warm air close to the body for exceptional insulation while simultaneously diverting sweat and dampness outward. Quick-drying and highly breathable, this base layer ensures optimal comfort across all climates.

  • Moisture Management: Actively wicks perspiration away from the skin to keep you dry.
