The versatile Sitka CORE Heavyweight Hoody is built with comfort stretch fleece insulation and a form-fitting hood to add warmth and concealment across a range of conditions. Offset seams on the shoulders improve range of motion and comfort while wearing a pack and thumb loops keep sleeves in place when donning and doffing to layer. Channeled fleece insulation adds breathability and works to control moisture buildup while Permanent Polygiene® Odor Control Technology neutralizes odor by stopping the growth of odor-causing bacteria and fungi during the long hike in. The Heavyweight series is your midlayer solution for static hunts in cold weather and active late-season days that demand a balance of warmth and breathability.
