Medium support

This sports bra has been built to minimize bounce without restricting your movement, it's got a higher neckline and light padding to help you feel secure and comfortable. Plus, reflective logos on the underband add a touch of luxury.

Adjustable straps

The Performance Bra Flex is an update of the original. We’ve added responsive, adjustable shoulder straps, soft padded cups, and we’ve upgraded the materials for added feel-good.

Sweat-wicking fabrics

Sweat-wicking fabric and a full mesh racerback panel for ventilation help your body stay cool and let it breathe. Sports scientists have tested these improved materials, and lab-based wearer trials have allowed us to perfect the fit.
