Breathable, ergonomic, comfortable: These are the key characteristics of the UYN(R) EVOLUTYON UNDERWEAR SHIRT LONGSLEEVE TURTLENECK made of Natex, a 100% organic nylon fibre for ideal climate management. Coolvent allows a constant air flow due to channels running through the inner surface. In this way, the shirt absorbs sweat and cools down the wearer during movement. With its innovative Hypermotion arm and shoulder construction - made from one piece and therefore seamless - it also guarantees maximum freedom of movement and supports the correct posture. Ideally, the longsleeve with stand-up collar is suited to sweaty, intensive sessions, especially in autumn or on warmer winter days.
