The Women's Core Lightweight Hoodie is the gold standard for performance in lightweight synthetic base layers. Equally efficient as a standalone piece in warm weather or as the next-to-skin foundation for every SITKA system, the advanced polyester knit construction wicks sweat and dries quickly. Polygiene(R) Odor Control Technology helps keep scent to a minimum. The built-in hood, stretch mesh facemask and thumb loops make it the complete package for comfort and concealment.
