Definitely does a good job of squishing everything in so running and moving isn't as painful. Maybe a little too much spillage out of the top of the bra, but whatever, not a huge deal.
As a busty gal with a small band size, it is difficult to find a supportive sports bra, and the ones that do provide support are so uncomfortable that I can barely wear them for an hour. Not so with this sports bra. It provides support without being restrictive. I wore it for several hours without complaint.
