Single track, several speeds: bike, run or hike with full coverage and summertime cool in our new Long-Sleeved Fore Runner Zip-Neck. Its ultralight, highly breathable and fast-wicking 100% recycled polyester fabric does the heavy lifting, while the deep front zipper (with chin guard for comfort) provides additional ventilation. Flatlock seams provide no-chafe, next-to-skin comfort, and a locker loop lets you dry it out afterward. The set-in sleeve design gives comfort and enhanced mobility, and the short self-fabric collar wicks moisture.. With 15-UPF sun protection, Polygiene permanent odor control and reflective logos on the left hem and center back neck. Fabric is bluesign approved.
