Technical Specifications

The foundation of layering
The Merino Base Tights use fine 19.5-micron Uruguayan Merino wool for exceptional softness and reliable next-to-skin performance. Naturally warm, breathable, and odor-resistant, they manage moisture efficiently during climbs, tours, and high-output days, while maintaining comfort across long, multi-day use. The wool’s natural stretch provides a stable, mobile fit that sits cleanly under shell pants without bulk, keeping you warm during pauses and dry during effort. Ethically sourced from low-intensity free-range farms and knitted in Portugal, they balance technical capability with craftsmanship and responsible production. Lightweight and adaptable across seasons, they perform on winter ascents, shoulder-season missions, and everyday cold-weather activity.
