There ain't no rest for the wicking--we'd call on this bra 8 days a week if we could. Comfortable enough to sleep in, sleek enough to work in, and yup, wicking enough to sweat in. Light support, smooth and silky seamless construction, racerback. Molded cups keep the twins separate. Polygiene® permanent odor control. XS(30BC-32AB), S(32BC-34AB), M(34BC-36AB), L(36BC-38AB), XL(38BC-40AB).
