I wear one, fully adjustable, with velcro back & shoulder straps, front zip, but I don't really use the front zip. It's not quite as smooth in front, there's seams, and removable pads, some may not like those features. This is the highest support bra they have, and it works well for running, super easy to exit post workout.
High intensity circuit workout, there I found it to be slightly restrictive, maybe some chafing too. Their medium support or next one down from that is not enough support for running, and didn't feel that it was much better than less expensive medium support bras. Amazon has a lower cost bra that's pretty good, not as adjustable, but works well, Syrokan, high impact, less fun to get in and out of.
I got the Shefit bra just now. I tried it on and after several attempts got it on. This one will work and no side spillage. Jumping up and down there was minimal movement and I am a G cup girl. I will let you know how it feels when I am actually working out in it.
