The Sport Science™ Men’s Wool Fleece Pullover is the only wool engineered specifically to wick moisture and keep you dry. Sport Science™ blended Dri-Release polyester into the top and toque's merino wool fabric. This gives you the even-when-wet insulation and odor-battling capability of merino as well as the moisture-wicking power of polyester. The men’s pullover has a snap collar and zip breast pocket. Stay warm. Stay dry.
