I'm a 36 DD. I like to stay active, but hate bounce.
This bra is perfectly adequate for low impact activities (yoga, weight lifting), but any activity that requires more movement (such as speed walking, basketball, running, off road biking) it fails miserably. If you jump up and down in this, its downright painful how much your breasts move up and down.
Furthermore, I found the bra unattractive under a t shirt. I've had the same experience with many other Shock Absorber bras.
I mainly use this bra with another low support bra to give adequate support. However, for this price, you are better off buying a couple of cheaper bras and using two at the same time. If you want a bra that you don't need to layer and that will eliminate bounce, keep looking. This is not the bra for you.
