R5 Base Merino T-Shirt Men | navy

Natural, functional, and ultra-comfortable: The Base Merino T 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 on 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 warm, warming when cold. The elastane content also makes the shirt highly flexible and guarantees maximum freedom of movement – whether hiking, climbing, or on alpine high tours. Merino wool also has natural odor-inhibiting properties, making it ideal for multi-day tours. Produced in Lithuania, the shirt stands for sustainable quality and durability.
