The Thermowave Warm men's long-sleeve merino shirt is a reliable base layer for all mountaineering, skiing, and hiking adventures on colder days. It is crafted from premium-quality 100% pure merino wool with an optimal fabric weight of 180 g/m², delivering excellent thermal insulation with minimal bulk. With a total weight of only around 180 g, it ensures the perfect balance between lightness and pleasant warmth.

The special ribbed knit structure effectively traps body heat while providing exceptional breathability and rapid moisture wicking away from the skin. Merino fibers act as a natural thermoregulator that keeps you warm even in damp conditions, while also boasting natural antibacterial properties that successfully prevent unpleasant odors and allow for multi-day, worry-free wear on longer treks.

The cut is carefully tailored to body movement, featuring an anatomical, snug fit (Next-to-skin) and raglan sleeves that eliminate pressure points around the shoulders. All connections are made with flatlock seams to prevent chafing under the weight of a backpack, while the extended drop-tail hem ensures the lower back stays securely protected against cold drafts.
