Race day support
Based on feedback from our athletes, we added vertical straps to the top's racerback construction for added stability and support. Bonded seams provide maximum on-skin comfort.

Front zip closure
The front zip closure allows for an easy-to-adapt fit, plus extra airflow when you want it. An internal flap behind the zipper protects skin from rubbing or chaffing.

Bonded underbust band
The bonded underbust band feels secure yet soft, for a close and comfortable fit when in motion. Taped mesh material adds a premium finish.
