This bra fits very well, is very supportive while running and other exercise. Yes, it's cotton so it will get sweaty, but if you're wearing it as a sports bra then you would expect to get sweaty.

I bought this in the same size as my regular Natori bra and it fit great. When I jog I feel very supported and it is more flattering then a typical sports bra if that's a concern for you.

This was worth the cost and I'm very pleased with my purchase.
