This bra is really great for exercising or just for daily wear, if you need as much support as I do.  The straps are visible when wearing some shirts, so watch for that.  I only had two problems with this bra: 1) it is hard to latch because it's a pullover, but it's not that bad; and 2) if I wear the bra too much it chafes a bit, but I think that is because it's so fitted.  I am a 36DDD and have never been able to find a good bra for running in, until now.
