I love my Enell sports bra. I am a 32 DD, and Enell eliminates any bouncing. Even while I am nursing. Running, even step aerobics, I literally have zero breast movement. It is a compression bra, so it took a little getting used to.
Down side is the price. I only have one, because it was $62.00. I hand wash it daily, and hang it up to dry. Other down side .... it is not flattering at all. Makes you look totally flat chested.
