Uyn Evolutyon SS base layer shirt

The evolution of the active world

Breathable, ergonomic, comfortable: UYN underwear is made of near-natural Natex thread for the best climate management and optimal bodily support. Ideal for a high level of physical activity and moderate temperatures.


The UYN-Coolvent concept is based on open fabric structures. Numerous channels permeate the inner surface to ensure a constant flow of air for optimum comfort. It absorbs perspiration quickly, cools the body during exercise, and keeps the skin comfortably dry thanks to its breathable properties.

Warms during rest phases. Insulating properties protect the body from cooling down after exercise, keeping it warm and ready for peak performance.

Exposed areas, e.g. the elbows, are designed to be especially tough and thermally insulating.

UYN Drylight technology allows the exchange of air and at the same time the insulation from the cold. Thanks to a light knitting and extremely absorptive technology it releases the humid air to the outside, preventing it from condensing. At the same time it allows an easy breathing while maintaining insulation.

Dynamic contour lines seamlessly interconnect the individual functional zones and guarantee even more wearing comfort and greater freedom of movement.

Cut from a single piece of fabric, innovative tailoring supports correct bodily posture and unrestricted freedom of movement.
