The Sitka Gear Core Heavyweight Hoodie was built with lofted fleece insulation and a form-fitting hood for added warmth and concealment. The CORE Heavyweight Hoodie keeps you from shivering on long, frigid stakeouts. Permanent Polygiene Odor Control Technology neutralizes odor by stopping the growth of odor-causing bacteria and fungi. The CORE Heavyweight Series is the next-to-skin foundation for static hunts in cold weather, with a body-mapped grid fleece backer that retains warmth while actively moving moisture away from the skin.
