Lab tested. Runner approved.

Not only did we partner with the Research Group in Breast Health at the University of Portsmouth to conduct extensive biomechanical testing on bras, we conducted almost 1,000 interviews. We sat down — or ran — with women and listened to their frustrations and learned what they love in a bra.

Support for all

Testing included how running affects breast movement on a wide range of sizes, not just the standard B cup. We found that women without a supportive bra lost 4 cm with every stride, over 1 mile over the course of a marathon. Our solve? Run-ready support that that sculpts to every body for minimized movement.

Distraction-free design

The combination of seamless support, chafing prevention, added airflow, and molded cups in our new run bras results in a distraction-free design that allows you to forget about your bra and focus on your run.
