From sexy balconettes to hard-working sports bras, racerback bras offer support, keep straps from slipping, and work well under close-cut tanks and sleeveless tops. And when racerback bras are fabricated from microfiber, the benefits also include breathability, softness and a smooth finish.
Some racerback microfiber bras have a cross-over strap design that moves with you. Most racerback styles also help prevent back fat. Combine that with the virtual invisibility of microfiber cups, and you'll have a versatile wardrobe addition to work under tees, knits and tanks.
