When temperatures cool off, layer up in lightweight activewear that keeps you comfortable. Cut from an innovative textile that gets warmer as it absorbs moisture, our women's Thermal Long Sleeve Shirt can raise your body temp up to 3° Celsius. The sleeves are designed with mittens to protect your hands as needed, and you can easily sport your technology with an in-built wrist hole and headphone hole. Like all of our running apparel, this women's top has reflective prints for safety in the dark. Finished with logo detailing.
