Merino 24 Hour Long Sleeve Crew – Men's

Built for athletes who need one shirt that handles a long day on the trail, at the crag, or in camp, the 24 Hour Crew is our top pick for guys who run hot and hate doing laundry. Pure merino wool regulates temperature and resists odor naturally, so you stay comfortable whether you're sweating hard or standing still. It layers clean under a shell and moves well enough to wear straight through.

• 100% merino wool construction — naturally temperature-regulating in Southern heat and cool mountain mornings alike
• Built-in odor resistance means you can wear it hard, day after day, without it getting funky between washes
• Moisture-wicking merino moves sweat away from skin and dries faster than cotton, keeping you from feeling soaked
• Slim enough to layer under a softshell or insulated piece without bunching or adding bulk
• Available in Black, Dried Tobacco, and Sitka — muted, versatile colorways that work from the trailhead to town
