The super comfy Coobie bra is a favorite at Lily! It's seamless, so no hooks or clasps. The back is smooth. Straps are adjustable & removable and each has removable, reversible padding. The pads stay in place with the versatile pocket that can be used to hold prosthetics in place of the pads. The fabric is made of an ultra soft nylon and spandex blend. Perfect for everyday wear, work, the gym, yoga, and so much more!
