The UYN base layer Energyon Sleeveless Men is suitable for intense sports activities with heavy perspiration. Holes of different diameters, three-dimensional micro-ribs and the combined use of polypropylene create exceptional airflow on the skin. In this way, excess body heat is immediately dissipated. In addition, the three-dimensional Coolvent fabric structure enables a constant flow of air. The fabric ensures that sweat is quickly absorbed and provides a cooling effect during movement. As a result, optimal comfort is maintained even after prolonged wear. Visually, it is rounded off by knitted-in logos, a crew neck as well as hem and arm cuffs with elastic edging.
