Who We Are

At Swijin, we take women seriously. The sports bra is not just a strappy accessory. It's a determinant of performance, pace, and pain.

Which is why we invested over 1 million Swiss Francs in research and development to revolutionize the single most important piece of athletic equipment a woman wears.

We call it an investment in the invisible: Everything that's been overlooked, unsaid and settled for in a sports bra.

We relentlessly pursued beautiful design, textile innovation and exceptional fit; scientifically supported and second to none.

We can't wait for you to experience Swijin, Swiss sports technology engineered by and for women.

Our Purpose

Swijin is bigger than a brand.
We’re a call to action.
An alliance of engineering and elegance.
A challenge to all assumptions about performance.
And a dare to all who would challenge us.
We are Swijin.
We take women seriously.
Established and created by - and for - women.
Engineered to be a promise, not just a product.
We’re a stand against the smallness of simple thinking.
An idea whose time has come.

From Swimrun Bras to the First Intelligent Sports Bra

While running during summer vacations, I longed to swim afterward, but my sports bra and shorts weren’t up to the challenge. After finding no hybrid gear that worked both on land and in water, I decided to create it myself. Collaborating with scientists and textile engineers at Swiss Federal Laboratories for Materials Science and Technology (Empa), we developed a fast-drying, high-tech fabric and designed the Swijin double-layer bra, offering land support and swimsuit-like compression.

After a newspaper article about our research, elite Swiss athletes approached us, seeking a sports bra that truly addressed their needs. Despite many sports bras on the market, none solved key issues: poor support, slow drying, chafing, and restrictive underbust bands.

This sparked a new mission: to reinvent the sports bra with input from sports physiologists, textile engineers, and elite athletes. We created bras with underbust bands that allow easy breathing, seamless designs to prevent chafing, and superior upper breast support for optimal performance.

At Swijin, we innovate with female anatomy in mind, taking women and athletes seriously. That’s my promise.
