THIS IS FOR YOU.

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.

How we work

Fearless By Design.

It can't just work. And it can’t just be pretty. It has to work beautifully. At Swijin, we create products engineered for high-performance athletes without compromise. Every product is designed to optimize performance while prioritizing comfort and women’s health. We integrate cutting-edge technology with a deep understanding of sports psychology and health research to ensure each bra supports your body and goals.

In pursuit of flawless, not fast. Our obsession is the overlooked, the unsaid, and the inconvenient. Our products combine the elegance and sophistication of Italian design with the technical demands of athletic wear. We believe that comfort, style, and performance can coexist. Swijin bras are meticulously crafted to offer the highest level of comfort while maintaining a fashion-forward look that enhances your confidence, whether training or competing.

We take a holistic approach to designing performance wear. Our team collaborates with sports psychologists, health experts, and textile innovators to understand the full spectrum of an athlete’s needs. We don’t just rely on research. We consult with athletes at every stage of our design process, ensuring that our products are built with real-world feedback. From advanced fabric technology to psychological well-being, we design products that support your body and mind, allowing you to perform at your best, both physically and mentally.

We are committed to innovation in every aspect of our design process. Swijin’s bras result from extensive research and testing, combining performance-driven textiles with sports psychology and health studies insights. We push the boundaries of textile innovation to ensure our products provide adaptive support, breathability, and stability for every woman’s unique body. We are re-imagining how products that have reached the end of their life can take on a new one. Unlike traditional return programs that down cycle products, we’re forging global partnerships at the forefront of circularity.

Every Swijin product is built to enhance your performance, not just support it. Our bras are designed to fit seamlessly, offering unrestricted movement and superior support. Whether you’re pushing for a personal best or simply striving for comfort during your workout, Swijin bras help you lift your game, empowering you to move freely and confidently.
