This is exactly what we've been looking for!!!! Purchased for my 14yr daughter. 34DD who is VERY active. She plays jrRoller Derby. Used to run until it became too painful. We've tried so many sports bras, even spent the day in a store once trying on bras. We actually thought we found one that she really liked (and she stopped complaining about). However I found myself very disappointed when I saw her running and not giving the effort that I knew her capable of. I ordered this bra on a whim, not really expecting much, but the look on her face as she tightened the straps made it totally worth the price! She says she feels like she did before puberty. It is amazing!! She wore it to practice for the first time last night and was amazing! I'm telling everyone I know about it!!
