Natural, soft and warm: The UYN(R) FUSYON UNDERWEAR SHIRT LONGSLEEVE 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(R) 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 does not restrict movement. Coolvent, a three-dimensional fabric structure, also guarantees a high level of breathability.
