Natural, soft and warm: The UYN® FUSYON UNDERWEAR SHIRT LONGSLEEVE TURTLENECK made from high-quality merino wool is particularly soft on the skin and is the ideal companion for every winter day. Whether you prefer to spend your time doing sports or staying comfortable – thanks to its material, combined with Heatmemory technology, it ensures efficient heat insulation – even after activities. UYN® combines premium wool with its innovative designs. This includes the Hypermotion cut: Shoulders and sleeves are made in one piece without seams, so the longsleeve with stand-up collar does not restrict movement. Coolvent, a three-dimensional fabric structure, also guarantees a high level of breathability.
