125 ZoneKnit Leggings – Men's

Built for high-output efforts in warm-to-cool conditions, the 125 ZoneKnit Leggings are our pick for trail runners and fastpackers who overheat in traditional base layers. Body-mapped eyelet mesh panels paired with a merino-TENCEL blend vent heat exactly where you need it, keeping you dry without sacrificing wool's natural odor resistance. Flatlock seams and a gusseted crotch mean zero distraction under shorts or pants.

• ZoneKnit body-mapping places breathable eyelet mesh panels over high-heat zones — targeted ventilation that outperforms a solid-knit base layer
• 125g Cool-Lite fabric blends ultralight merino wool with TENCEL Lyocell for natural moisture-wicking, temperature regulation, and multi-day odor resistance
• Gusseted crotch and flatlock seams throughout allow full leg mobility with zero chafing under technical shorts or softshell pants
• Ideal for trail running, fastpacking, mountain hiking, and cold-weather layering when output is high and conditions are unpredictable
• Available in Black/Jet Heather and Geo Blue/Royal Navy — sizes M through XL
