I purchased this sports bra for my mother and I, and we both agreed that this bra offers the best support during medium to high impact exercises. I enjoy running, but I always felt uncomfortable due to my breast size. With this bra there is very little movement, and it is very comfortable without having to appear as if you only have one breast! I love this sports bra so much that I have bought another one since this purchase. However, It is important that you go to the moving comfort website and take measurements and go by their size chart, because it is not the same as your regular bra size. I am very pleased with the moving comfort sports bra!
