All-weather warmth never looked so stylish. New Balance Women's NB Heat Run Jacket features a modern color block appearance with leading-edge functionality like NB Heat gridded fleece and a wind- and water-resistant overlay. Two zippered hand pockets safely stash essentials for pre- and post-workout errand runs. NB Heat fleece captures heat while wicking sweat away for dry, lightweight warmth. Plus, hidden thumbholes offer added protection while keeping the sleeves from riding up.
