Overview

Built for cold-weather layering, these heavyweight thermal bottoms are suited to long sits, early starts, and other demanding days in the field. The waffle-knit polyester and elastane blend is paired with Force FastDry technology to help manage moisture, while Rugged Flex stretch supports movement when you’re climbing, kneeling, or covering ground. Smooth flatlock seams are a practical touch for reducing chafing under outer layers.

Considerations & Trade-offs

  • Heavyweight construction is geared toward cold conditions, so it may feel warmer than needed during milder hunts or high-output activity.
  • The stretch fit is designed for movement, but base-layer sizing and layering preference can affect how it feels under outerwear.
  • As a thermal bottom, it is intended as a layering piece rather than a standalone garment.
  • Performance features like FastDry and odor control are useful, but they do not eliminate the need to manage moisture and layering in the field.
