I really use care with sports bras, I have tried many over the years. I particularly like racer backs so I gave this bra a try and was somewhat disappointed. It has a very cool look and it's thick and supportive for medium impact. It has no underwires but lifts and holds breasts in nicely. However, after 10 minutes of high impact weighted cardio using a step, the left strap popped open. I spent about 2 minutes fiddling with it to get it in the right position. It was easy to fix but who wants that? I'd rather have a full on industrial strength iron bra, like Champion Powerback or Moving Comfort Maia than a bra that has some cool features but pops open. I'll keep it and use it but I'm going to stick with my faves, Powerback is the bomb in sports bras, Maia 2nd.
