Racerback Bra
Racerback bras are also called T-back and sportback bras. A racer-back bra is any design for the back that allows maximum movement of the back and arms. It can have a high curve near the neckline with a T-strap down the center back; have bra straps attached close together on a back with a center back panel; or have cut-outs around the shoulder blades.
Because of the back design, a racer-back bra will most commonly be front closure. It therefore has all the front closure challenges mentioned above. The strap placement may also be too close to your neck, pushing down on your cervical nerve, which runs from your neck to your shoulders. Therefore, headaches, neck pain, numbness and shoulder pain are frequent complaints by women who have tried racer-back bras.
