Racerback Sports Bras are named after racing swimsuits that also have straps meeting in a āVā shape on the back between the shoulder blades. This sports bra style is an excellent solution for sleeveless workout tops. It also prevents the shoulder straps from slipping off the shoulders. Most important, a racerback sports bra offers more support to the breasts. This additional support is especially necessary for full-busted and full-figure women. Since the shoulder straps are centered closer together in a racerback sports bra, this also offers more support to the back. HerRoom offers a wide selection of racerback sports bras as well as free shipping, customer reviews, detailed product descriptions and several different photographs of each item.
