Apparently evolution saw fit to deny us a decent natural warming system (see also "fur"). The Dynafit Women's Gallium Pullover Top will put you back into competition. Technostretch fabric's waffle texture excels at trapping warmth and releasing odor. The unmatched four-way stretch athletic fit and thumb-holes hug your every movement, making the Gallium Pullover an ideal mid-layer as well. Use your massively evolved brain to naturally select this light-weight pullover when running, skiing, or just climbing the food chain.
