I've been on a quest for a good sports bra. I used to use a cotton Champion jogbra, and realized I needed something much better. I switched to the CW-X sport support bra, which offered me good support (I'm a 34D), but didn't have good ventilation and felt a little smothering. I then tried the CW-X xtra support bra, which had better ventilation, but felt even more constricting -- great support, though. I then tried this one. It's less constricting than the CW-X bras and has much more ventilation. It's support isn't quite as good, but it's adequate. What's bizarre about this bra is that the elastic has a weird papery feel, which feels kind of poke-y when you first put it on. Once you get it wet, its fine, but the initial feel isn't great.
