For high-output trail runs and fast hikes where heat buildup kills your pace, the 125 ZoneKnit is our top pick for athletes who run hot. Zoned merino construction places lighter mesh panels exactly where you sweat hardest, so heat escapes before it stacks up. At 125 gsm, it's light enough for Southern summers while still fighting odor across multi-day efforts.

- Zoned merino mesh panels target high-sweat areas for active ventilation right where you need it most
- 125 gsm ultralight merino wool — itch-free, naturally odor-resistant, and breathable enough for warm, humid conditions
- Crew neckline sits low and clean so it layers under a vest or pack harness without bunching or riding up
- Built for high-aerobic efforts in Southern heat — trail runs, fast hikes, and any activity where you're working too hard to slow down
- Merino regulates both ways — pulls heat out when you're pushing, holds warmth when you stop moving
