Run. Swim. Run Again.

(Wardrobe change not required.)

Founded by two life-long friends, Swijin innovates beautiful, hybrid performance wear that simplifies your life. Here’s the story on how we got started, where we’re going, and what you can do to join in!

Our product idea came to us in the summer of 2020 out of a shared problem we faced on opposite sides of the Atlantic: During our morning runs to the beaches of Miami and Mallorca, we arrived at the ocean hot and sweaty and desperate to combine our workout with a swim. We were frustrated that our sports bras and bottoms didn’t function as swimwear. 

On a phone call commiserating about our shared frustrations, we decided to realize a hybrid invention allowing athletes to alternate between land and water sports fluidly, without having to change, while being a role model for sustainable production.


We embark on our journey to create supportive, incredibly comfortable sports bras and bottoms that dry in a flash and double as swimwear.

Swijin partners with Empa, the Swiss Federal Laboratories for Material Science and Technology to develop our solution. 

Swijin is incubated by Startfeld in St.Gallen, Switzerland.

Our science-based innovation is granted funding by Innosuisse, the Swiss Innovation Agency, which supports small businesses in developing new types of products. 


Live-testing our prototypes with female Swimrun athletes in Sweden and USA. 


Go to market with a mix-and-match Swimrun set, both bras and bottoms, specifically designed to address the problems of female Swimrunners.
