R5 Base Merino Long Sleeve Shirt Men | black

Natural, functional, and ultra-comfortable: The Base Merino Shirt Long M is the perfect first layer for mountaineers who value quality, lightness, and freedom of movement above all else. Made from the finest merino wool with a fiber thickness of just 17.5 microns, it offers a particularly pleasant feel directly against the skin – soft, light, and non-scratchy.

Thanks to the lightweight material and the natural thermoregulation of Merino, you always stay in your comfort zone: cooling when it's warm, warming when it's cold. The elastane content also makes the shirt highly flexible and guarantees maximum freedom of movement – whether hiking, climbing, or on high alpine tours. Merino wool is also naturally odor-inhibiting, making it ideal for multi-day tours. Produced in Lithuania, the shirt stands for sustainable quality and longevity.
