The xLeisure Modern Sports Bra ($53, originally $79) strikes the perfect balance between performance-ready and stylish. Made out of a special second-skin xMembrane® Pro+ fabric, it features a stylish quad-crisscross back for support. As soon as I put this one on, I knew it would be perfect for my functional training workouts, and the breathability, sweat-wicking fabric, cooling fibre, and comfortable stretch proved me right.
