Built for cold-weather tours and deep-winter freeriding, the 185 Rock’N’Wool Long Pants deliver pure comfort using 100% fine merino wool. The ultra-soft 19-micron fibers feel smooth against the skin, never itchy, and naturally regulate temperature and moisture to maintain a stable microclimate during long ascents or high-effort descents.
At 185 g/m², this midweight merino base layer provides reliable warmth without bulk, making it ideal beneath touring pants or freeride shells. The updated design features a distinctive split color pattern, multi-colored twisted yarn, and a modern, flexible waistband that stays put during movement.
Naturally odor-resistant, breathable, and renewable, these long pants bring dependable performance to every cold-weather mission—from storm-day laps to high-alpine objectives.
