A stretchy merino baselayer shirt ideal for long, high-output days on the bike, trail, skis or the rock, the updated 200 Zone Long Sleeve Crewe is the ultimate lightweight technical baselayer top. The Zone features our BodyfitZONE™ construction, which combines lightweight, odor-resistant stretch merino wool with strategically placed merino mesh panels to help regulate temperature during stop-and-go days on the trail or in the mountains. Raglan sleeves and underarm gussets allow for unrestricted range of motion, and flatlock stitching eliminates chafing during dynamic days out in nature.
