With breathable heavyweight fleece insulation and articulated patterning the Sitka Big Game Open Country CORE Heavyweight Bottom keeps the lower limbs warm during long periods of frigid inactivity while wicking moisture when on the move. With a comfort stretch fleece for warmth and channeled construction for added breathability and moisture management, the Heavyweight Bottom is a perfect midlayer for static hunts in cold weather and active late-season days. Permanent Polygiene® Odor Control Technology neutralizes odor by stopping the growth of odor-causing bacteria. Minimal seaming, low-profile flat lock seam construction, and a low-profile elastic waistband provide the highest tier of comfort as you layer and adapt to your conditions.
