Our Hollow Sports Bra is our simple yet sexy Sports Bra. Hollow is a very fine Nylon & Spandex Blend that is sweat-wicking, breathable, and quick dry. Hollow is a high-impact bra with a lot of support for the breast region. Hallow gets the name due to the back of the sports bra being carved out and leaving the upper back visible. This Bra has a removal pad as well. ( PLEASE READ SUGGESTIONS BEFORE PUCHASE)
