Designed specifically as a next-to-skin base layer, the Core shirt from Sitka Gear is designed for early season hunting, when temperatures are still soaring. The 4-way stretch fabric adds durability and allows for full range of motion. Raglan- style shoulder and flatlock seam construction keep you comfortable and in the field longer. The Core is specifically designed to wick moisture away from the skin, but still aids in keeping your warm on chilly morning or evening hunts. The silver-encapsulated scent technology reduces odor-causing bacteria, allowing you to get close to your quarry. Weighs just 8.51 oz.
