Level I: Light-Weight Undershirt & Drawers

Base Layer: Worn next to skin by itself or in conjunction with other levels for added insulation and to aid in the transfer of moisture.

The GEN III Light-Weight Undershirt and Drawers are designed to wick moisture and to provide protection from the elements.

Constructed with Polartec® Power Dry® Silkweight material, this layer is highly breathable, wicks moisture away from the skin and dries fast, providing evaporative cooling in warmer weather and insulating in cool weather – all with less weight and bulk than previous systems.

How Does Polartec® Power Dry® Work?


  1. Moisture and high relative humidity next to the skin causes discomfort. Polartec® Power Dry® keeps the skin dry through three complimentary mechanisms:
  2. The fabric is highly breathable and does not restrict the movement of moisture vapor.
  3. “Touch points“ on the fabric’s inner surface draw off the sweat. Sweat is wicked off the skin to the outside of the fabric where it spreads rapidly for evaporation. Polartec® Power Dry® fabrics move at least 30% more moisture away from the skin than single component fabrics.
  4. When the sweat reaches the outside of the fabric, it spreads out to many times its original surface area, enabling it to dry at least 2 times faster than cotton.
