The Core Lightweight Hoody is designed to be more than just a shirt. A built-in face mask and low-profile hood for instant concealment, 1/2 length zipper to release heat, and chest pocket to store reeds pack more of a punch than competing baselayers. SITKA’s high-performance polyester moves moisture away from your skin to evaporate during periods of high exertion while drying quickly during low exertion periods spent sitting, glassing, or calling.
