I've been wearing this sports bra during karate classes and it's been fantastic. I don't bounce much despite jumping jacks, and other movement. I really like that I can clip the straps together to make it a T-back. It provides the best support out of all the sports bras that I have tried.

It is true to size. I wear a 36H (UK) and got a 36H in this bra. The cups were just a touch big, but it wasn't a big deal.
