Salewa Cristallo Warm Men's Alpine Merino Responsive Thermal Shirt - Black Out

The Salewa Cristallo Warm thermal shirt sets a new standard for cold-weather base layers by combining the natural performance of fine Merino wool with the advanced thermo-reactive Responsive technology. Unlike ordinary merino baselayers that simply insulate, this shirt actively works with your body heat to enhance warmth and recovery, making it a standout choice for alpine mountaineering, ski touring, and demanding treks in frigid conditions.

Highlights

• Alpine Merino Responsive fabric: 83% virgin Merino wool, 17% polyamide for durability and stretch
• Thermo-reactive Responsive minerals convert body heat into far-infrared energy, boosting warmth and aiding muscle recovery
• Naturally odor-resistant and moisture-wicking Merino wool keeps you fresh and dry during high-output activities
• Athletic fit with gusseted sleeves and 4-way stretch allows unrestricted movement on technical terrain
• Flatlock seams prevent chafing under pack straps and harnesses
• bluesign® approved fabric ensures sustainable and responsible manufacturing

In daily use

On cold alpine starts, the Cristallo Warm delivers immediate comfort with its soft, itch-free Merino interior. The Responsive technology adds a noticeable warmth boost without extra bulk, while the quick-drying fabric manages sweat efficiently during intense climbs or ski ascents. The crew neck and long sleeves provide full coverage, and the athletic fit layers smoothly under midlayers and shells. Whether you're breaking trail on a ski tour or belaying in the shade, this shirt maintains a balanced microclimate, reducing the chill after stops and keeping you comfortable all day.
