The HECS High Performance Baselayer Shirt combines a snug fit along with a semi-thermal, high-performance wicking fabric to keep hunters comfortable against any type of elements. You will be comfortable in this shirt during a winter hunt and also while you are on a spring hunt. The HECS patented conductive grid is woven into the fabric and allows you to get close to animals without disturbing them. The prey will sense an inanimate object rather than a human being.
