UYN Fusyon Light thermal shirt

Thanks to the combination of merino wool and UYN technologies, this short-sleeved UYN ENERGYON MERINO underwear keeps your body dry and at the ideal comfort temperature while ensuring excellent skin comfort. The body-mapped construction features the exclusive FLOWTUNNELS ventilation system in areas with high perspiration (chest and back): the combination of holes and 3D channels promotes air circulation and creates a perfect microclimate on the body. The sleeves and shoulders are equipped with the patented HYPERMOTION technology, which guarantees complete freedom of movement. UYN ENERGYON MERINO is the ultra-versatile underwear, ideal for all outdoor activities in moderate to low temperatures.
