Not every piece in The North Face's Summit Series is designed to be seen. The Summit Altimetro top was created to meet the demands of cold-weather trail running, where managing moisture, regulating temperature and keeping weight to a minimum matter most. Dot Knit™ and Flash Dry-Pro™ technologies work together to move sweat away from the body, helping you stay dry and comfortable when the pace picks up. The kind of performance layer that earns its place long before the conditions turn against you. 90% Recycled Polyester, 10% Elastane with Flash Dry-Pro™ Crewneck Thumb Hole Detail Reflective Branding Style Code: NF0A8DDXJK3
