Active Ultralite Long Sleeve – Men's

Built for high-output days when you need coverage without the weight, the Active Ultralite is our pick for trail runners and hikers who want merino versatility year-round. The ultralight merino blend wicks moisture and kills odor naturally, so you can push hard in Southern heat without that synthetic stench. Flatlock seams keep chafe out of the equation on long efforts.

• Ultralight merino wool blend delivers breathable, next-to-skin comfort without the bulk of heavier base layers
• Natural moisture-wicking and odor-resistance let you go longer between washes — critical on multi-day trips
• Flatlock seam construction eliminates chafing hot spots during high-mileage runs or all-day hikes
• Regular fit with four-way stretch moves with you on technical terrain without feeling restrictive
• Available in Charcoal Heather, Nightfall Blue, Burnt Sienna, and Pool Blue — transitions cleanly from trail to town
