As useful as it is classic - the T Long offers the full-coverage warmth and wicking properties of a high-tech long-sleeve T. Layer it under insulation when you're above tree line or pull it on for a dawn trail run - the T Long won't let you down. A wicking finish pulls moisture off your skin and the Ciba antimicrobial treatment beats pit-stink during a long day. Contrasted arm bands distinguish the piece from bland imitations and a semi-relaxed fit means all-day comfort no matter your activity.
