Roxy Cross Back Seamless sports bra. Lightweight and breathable with a seamless construction that slides softly over the skin, the Cross Back Seamless Bra is very simply a pleasure to wear. Its pretty, crossover back design also keeps things in place, delivering all-purpose comfort and light support. The rich, heathered fabric takes color beautifully, as well as wicking sweat away from your skin and actively dispersing excess heat. 92% nylon/8% spandex. Machine wash. Imported.
