The Thermowave Merino Warm men's short-sleeve thermal T-shirt, weighing approximately 150 g, offers an outstanding balance of thermal insulation, lightweight feel, and breathability. Designed as a reliable base layer for demanding activities in cooler conditions, it is ideal for mountaineering, ski touring, winter hiking, travel, or camping in the wild.

The shirt is crafted from 100% merino wool with a specific fabric weight of 180 g/m². Fine natural merino fibers feature a purposeful ribbed structure that efficiently traps body heat with minimal fabric bulk, making it ideal for layering. Merino wool naturally regulates body temperature, wicks moisture away, and utilizes inherent antibacterial properties to prevent unpleasant odors, even during multi-day wear.

An ergonomic, slim fit contours closely to the body and moves with you. Raglan sleeves ensure unrestricted freedom of movement in the shoulders, while the advanced construction with soft flatlock seams eliminates chafing under backpack straps. For complete protection against cold drafts, a thoughtfully designed drop-tail hem keeps your lower back covered with every bend and stride.
