The Sensor Active men's merino long-sleeve shirt is an essential base layer for all seasons and a wide variety of outdoor activities, from hiking and mountaineering to ski touring and running. It is crafted from 100% merino wool of the highest quality, sourced from certified New Zealand farms. The fine, long fibers ensure exceptional softness and a pleasant feel against the skin without any itchiness.

The fabric with a versatile medium weight of 160 g/m² offers the perfect balance between thermal insulation and breathability. Merino wool features natural thermoregulation – warming comfortably in the cold and helping to cool the body on warmer days through efficient moisture wicking. A remarkable advantage of natural wool is that it retains its insulating properties even when damp.

Thanks to the natural lanolin content, the shirt provides permanent antibacterial protection that prevents the growth of microorganisms and unpleasant odors, remaining fresh even after several consecutive days of wear. For extra protection during high-altitude adventures, it features a sun protection factor of UPF 25.

The cut adapts smoothly to body movement, while flatlock seams prevent chafing even when carrying a heavy backpack. With an exceptionally low weight of only around 190 g, the shirt is comfortable to wear and practical for any packing list.
