Nike Sportswear Classic Puffer Women's Therma-FIT Loose Vest is designed to add some warmth to your life. Loose enough to layer, the synthetic fill of this vest adds insulation, while Nike Therma-FIT technology helps manage your body's natural heat to help keep you warm in cold-weather conditions. On top of that, a water-repellent finish helps keep you dry. So zip it up, throw your hands in the pockets, and get out there!
