The Sensor MERINO DF CLUB kid’s T-shirt with long sleeves is made of a blend of polyester and high-quality merino wool from New Zealand. The main advantage of this combination is that the polyester accelerates the transport of sweat to the outer wool layer that has unique anti-odour and thermoregulation properties. The thin polyester layer protects sensitive skin from itchiness caused by the wool. The T-shirt is reversible and perfect for doing sports in extreme climatic conditions, such as high-altitude hiking, ski mountaineering and rock climbing.
