I got two of these (this one and the gray one) for wearing in Jiu jitsu after one of my bras didn't provide nearly enough support. The bands on this style run small. I'm normally a 28D/30C, and I needed a 32C. Otherwise it's got really great support!
I bought this to wear for jiu-jitsu because the style they recommended for martial arts doesn't come in my size. The band for this style runs small; I normally wear a 30V but needed a 32C for a proper fit. Otherwise it's a good, supportive bra for working out in.
I have two of these: white and black, and they've fitted well for almost 4 years. They're reaching the end of their lives now though. (and I'm not sure a new 32C would fit me still!) Offers great support even during running, and this is a really comfy bra. I'll probably continue to wear them for a while as 'normal' bras under some clothes. So: thank you Shock Absorber!
I've 'outgrown' this bra with my recent increase in cup size, so it doesn't fit well in the cups any more. Band is surprisingly small for a 32, and the whole bra just offers much compression. It still does what it's supposed to do when I'm running, despite the fit not being perfect and it stays in place due to the fact that it's not just the band but the whole thing that stays put on your body. I do find the back construction a bit uncomfortable over my shoulderblades
