Freedom of movement and comfort

Thanks to its innovative fabric construction, our performance flex jersey offers a great deal of flexibility and freedom of movement. This allows us to create the perfect fit that is close-fitting but not restrictive.

Dimensional stability

Our multidirectional stretch ensures high dimensional stability and resilience, which prevents wear and creasing in the long term.

Suitability for travel

The combination of ultra-fine microfibers with Lycra makes the fabric particularly lightweight. In combination with a special knitting technique, the fabric always remains particularly smooth, making it ideal for traveling and on the go.
