We are INA KESS.

INA KESS is a family of passionate and ambitious women. Initiated by the two sisters Katharina and Isabelle Staub in 2015, we create high-quality essentials, in which our customers feel great in every situation.

For this we have rethought the development of highly functional and at the same time beautiful sportswear. So today INA KESS stands for innovative, timeless designs that we combine with the functionality of modern activewear.


Our team.

We love feminine cuts, intelligent details and smart fabrics that offer maximum comfort in every situation. For the demanding everyday life of active women.



We want to keep our transport routes short. Therefore we produce all our clothes in Europe, mainly in Portugal.

Our producers are family-run businesses with whom we share not only good, long-term partnerships, but also the same high standards of quality and sustainability.


Katharina has undertaken many trips to Portugal to find the best partners. Here she is at one of our factories in the north of Portugal, about one hour from Porto.



We always want more. More functionality. More wearing comfort. More quality.

That's why we only use light, breathable, quick-drying and highly elastic fabrics. We find these in Italy, France, Portugal and Switzerland. And we test very carefully to make sure they meet our - and your - high standards.



Our products are available in selected boutiques in Europe and Switzerland. And of course  in our INA KESS Store in Zurich.

Subtle colours and cozy elements make our Store particularly friendly. We love to combine vintage pieces with a modern, sleek look. 

It’s a place of exchange, where our customers can experience the collections with all their senses.

We are happy to take our time to advise you personally. Just drop by - we are open for you from Monday to Friday from 10:00-19:00.



We love intelligent designs, functional fabrics - and our store cats Barney and Alfred.

Barney is already an older gentleman and likes to show the younger Alfred how things work here. Both are always curious, smart and warm-hearted, and thus fit perfectly into our team.

 Barney and Alfred, our cats, love to be part of the daily life at INA KESS. 


Thank you for following our journey.
