The North Face - Women's Summit Altimetro Long-Sleeve Top

Lightweight and engineered with a generous amount of stretch for a superior range of motion, the Summit Altimetro Long-Sleeve Top is specifically designed to meet the weight requirements of cold-weather mandatory race kits. Crafted from a mixture of recycled materials, DotKnit™ and FlashDry™ technologies, the body-mapped fabric reduces weight and increases comfort with a backpack, leaving you free to focus on what's in front of you.
