... I'm buying two more today. Although this seems to confuse the sizing issues other reviewers have mentioned even more, I got the medium and it fits me great, even though I'm 5'1", 34B, 122lbs (yeah, I'm a bit "stockier" than most of the ladies who are brave enough to put their sizes out here, but hopefully the info will help someone else determine their size). I wear mine to climb in and LOVE it. It moves with me but stays put around my rib cage and doesn't ride up under the girls like all the other bras do. I don't know if it would be supportive enough to run in, but for climbing, it rocks... no pun intended. The only down side is that I still get the unaboob with this bra. That said, I haven't found a solution to that in a non-separated cups sports bra yet, so I'm not going to worry about it. Definitely recommended, especially at such a great sale price.
I have a big chest (34DD). It's very difficult to find a bra that is comfortable. This bra does its job. I don't love it on its own, but if I put a regular bra under it to help keep things in place, I can do medium-impact activity very comfortably. It's definitely above average, but not perfect.
