With COOL.SKIN, we deliberately avoided using artificial brighteners to minimize the shirt showing through under the white business shirt.


Our functional shirt is made in Germany from the yarn to the knitter to the finisher to the ready-made clothing manufacturer.

By the way:
COOL.SKIN can be worn as an undershirt, but also as a classic T-shirt thanks to the understated design.

Outlast® phase change materials (PCM) can absorb, store and release body heat. As a result, the body does not have to start sweating to achieve cooling. The Outlast® technology starts very early and works actively and extremely hygienically: The formation of sweat is already reduced here. This is revolutionary and unique.
