If you're like me and laugh at most of the "sports bras" out there (glorified shelf tanks) you will love this bra. Yes, nips might be visibly hard with just this bra and a t-shirt, but I find a thin tank-top underneath a t-shirt will do the trick; yes, it's a bit awkward to put on, but once strapped in, the girls aren't going ANYWHERE. In my book, small prices to pay for complete comfort when doing any impact exercise.
