If you do any kind of activity that makes your breast bounce up and down you should consider wearing a sport bra. Your breasts do not contain any supportive components such as bones or muscles. Breasts are mostly made of fatty tissue and mammary glands. Most of the support comes from the skin that surrounds the bust and some ligaments. Once the ligaments and skin are stretched from excessive movement there is no way to undo it. Therefore the right support through the correct bra is necessary.
The double layer cups with the integrated wonder wire design prevent the underwire from ever touching your body. Feel supported in comfort like never before
