The North Face says about the Flex 1/4 Zip Women's
Work up a sweat and still stay dry in our Flex 1/4 Zip Long-Sleeve Top. Perfect for training, it’s made from FlashDry™ fabric that pulls moisture away from your skin so that it can evaporate away, keeping you comfortable as your body works harder. Pull the zip down for a welcome burst of fresh air as you up the intensity.
