Remember the "training bra" you got in the sixth grade? This ain't it. This is for the kind of training that involves 9-mile runs and full-contact sports. I'm a 38C and always looking for better motion control, and this bra really delivers. It provides great stability, even during high-impact activities. My only complaint is that the 70% cotton material does not wick as well as other sports bras that I own, which can leave one feeling a bit moist after a long training session. But, if you haven't already invested in wicking shirts, then it doesn't much matter if your bra wicks well or not, so that may not be important to you. Another plus of this bra is that it's very comfortable, despite being an underwire bra. The straps are relatively wide across the top of the shoulder, and they stay in place even with a lot of arm movement. I read one review that complained that the bra comes up too high on the chest, making it impractical to wear underneath low-cut gym tops. Hmmm. If you are worried about looking good while working out, this bra might not be right for you anyway. It seems to be designed for the kind of workout that gets you too sweaty for meeting "Mr. Right".
