About Us

At Riesin, we believe that everyone deserves to feel confident, stylish and strong no matter where life takes them. Founded in Aotearoa by two sisters, Mattesin and Marie, Riesin is a reflection of our shared passion for fitness and empowerment.

Our mission is to empower people, with thoughtfully designed athleisure that blends comfort, performance, and style. We’re here to help you feel your best—whether you’re at the gym, on the go, or simply taking time for yourself.

Pronounced "ree-sin" our name combines Rie (from Marie) and Sin (from Mattesin), symbolizing our commitment to rising together and uplifting people everywhere. The word "reason" is also embedded in our name, as we want everyone to find their reason and thrive with Riesin.

Join us as we redefine athleisure and inspire people everywhere to rise with confidence and style.
