Classic All-Season Merino Base Layer Bottom – Men's

When your day swings from a cold pre-dawn start to sweaty midday miles, this base layer handles both ends without complaint. Merino wool naturally regulates temperature and resists odor, so you stay fresh across back-to-back days in the field or on the trail. A slim cut and flatlock seams keep it invisible under any layer you stack on top.

• Merino wool construction regulates body temperature naturally across changing conditions — no synthetic clammy feel when your pace drops
• Built-in odor resistance holds up through multi-day hunts, thru-hike stretches, or back-to-back training days without the funk synthetics trap
• Slim, low-profile fit slides cleanly under hiking pants, hunting layers, or ski bibs without bunching, riding up, or adding bulk
• Flatlock seam construction eliminates chafe points on long days — critical when you're covering serious miles or hours in the backcountry
• Available in Black, Iron Heather, and Twilight Blue in sizes S–XXL — year-round versatility whether you run hot or cold
