The details are what make this piece worth talking about

With light insulation and a high zippered neck for fine-tuning your microclimate, the CORE Midweight Zip-T turns up the heat to keep you moving in frigid temperatures. Permanent Polygiene® Odor Control Technology neutralizes odor by stopping the growth of odor-causing bacteria and fungi. The CORE Midweight Series is the next-to-skin foundation for active hunts in cold weather, built with a micro-grid fleece backer that lightly insulates while actively moving moisture away from the skin.

“The Core Midweight Zip-Tis one of the most critical pieces of my whitetail arsenal. Any whitetail hunter understands the importance of scent control and reducing your human odor. In the morning or evening walk to my treestand, I strip my heavy layers off and get down to the Core Midweight Zip-T. I typically unzip the shirt completely. This tactic dramatically reduces my level of perspiration and odor. Upon reaching my stand, I will allow my body to naturally cool down and then layer up for the long sits.” — Sitka Athlete Bobby Warner
