Technical Specifications
The foundation of layering
The Merino Base Top combines high-performance function with the natural comfort of fine Uruguayan Merino wool. Its 19.5-micron fibers provide exceptional softness against the skin while delivering the technical qualities needed for full days in the mountains: natural temperature regulation, efficient moisture transport, and reliable odor resistance for multi-day use. The wool’s inherent stretch creates a close, mobile fit that works seamlessly under shells or mid layers, keeping you warm when you pause and dry when you push harder. Sourced from low-intensity, free-range farms and knitted in Portugal, it reflects a blend of craftsmanship, ethical production, and timeless design. Lightweight, breathable, and adaptable across seasons, it performs equally well on winter tours, cool-weather hikes, and year-round mountain travel.
