If you love the fit and simple styling on Zoot's Performance Racerback top, but want a little more freedom than the top's built in shelf bra provides, Zoot understands. It's exactly why it created the Performance BYOB Tri Tank Top. While the Performance BYOB doesn't provide roomy enough pockets for you to bring your own cold, refreshing beverages to celebrate post race as its name would suggest, it does allow you to race in your favorite bra, which is arguably a more valuable thing. Made with a lightweight, breathable blend of Performance Endura and Power Mesh fabric, the Performance BYOB employs a more forgiving fit than most race ready, next to skin pieces do, giving you room to move around freely throughout a race or training session while the fabric efficiently draws moisture away from your skin to evaporate quickly at the surface. The rapidly drying fabric will keep you comfortable and less likely to experience chafing, and Zoot thoughtfully included an extended back hem to provide welcome additional coverage over slim race shorts, with two side pockets to give you space to store nutrition.
