Men’s underwear

The comfort of any mountain adventure begins right against your skin. A high-quality base layer plays the essential role of regulating body temperature and quickly wicking away moisture, keeping you dry during intense exertion and warm during rest stops. Welcome to the men's technical and thermal underwear selection at Alternativa Sport. In our online store and at our shop in Sistiana, we offer a premium range of thermal shirts, tights, and technical boxers designed for skiing, trekking, mountaineering, and winter outdoor activities.

Our collection features targeted solutions for every weather condition and performance need. Discover pure merino wool or merino-blend base layers, which offer natural warmth, exceptional softness, and inherent anti-odor properties that keep you fresh even after hours on the trail. If you require maximum drying speed and stretch for high-intensity sports like ski touring or trail running, explore our technical underwear made from advanced synthetic fibers, featuring body-mapping structures and zoned ventilation where you sweat the most.

Engineered with ergonomic cuts, flatlock seams to prevent chafing, and premium yarns, our men's base layers fit like a second skin to support your every move. Explore the men's underwear category at Alternativa Sport and select the perfect thermal foundation for your alpine pursuits!
