A stretchy merino base layer shirt ideal for long, high-output days on the bike, trail, skis, or the rock, the 200 Zone Long Sleeve Crewe is the ultimate active base layer top. The Zone features our BodyfitZONE™ construction, which combines lightweight stretch merino wool jersey fabric with strategically placed merino mesh panels to improve ventilation and help regulate temperature during stop-and-go days on the trail or in the mountains. Flatlock stitching eliminates chafing during day after day of dynamic motion.
