Salewa Cristallo Men's Thermal Leggings - Merino Wool Base Layer for Alpine Mountaineering

Men's thermal leggings built for high-output alpine pursuits, the Salewa Cristallo leverages a thermoreactive merino wool blend to actively regulate body temperature during intense activity. Responsive technology uses natural minerals to recycle body heat, while the 150 g/m² fabric strikes a perfect balance between warmth and breathability.

Advantages

The Cristallo excels in moisture management, wicking sweat away from the skin and drying quickly to keep you comfortable during stop-and-go activities. Merino wool naturally resists odors, allowing multi-day use without washing. The 4-way stretch fabric and athletic fit ensure unrestricted movement, while flatlock seams prevent chafing under pack straps or harnesses. The elastic waistband stays securely in place, and the polyamide content enhances durability for rugged alpine terrain.
