Bought this recently to train for and run my half maraton this weekend. I also have a MC Fiona that has been fabulous. I think this provides equal or perhaps slightly better protection than the Fiona. As a DD cup, it is nearly impossible to have zero bounce unles perhaps one uses duct tape, but this bra does a really good job ensuring that things stay relatively stable and there is no disccomfort before, during or after a run. This is truly a high impact product.

Pros
No front adjustment/velcro strap/chafe potential like Fiona
Band doesn't seem to roll at the bottom like Fiona
Cons
As a nursing mom, I like the front opening when I go to the gym and nurse baby to sleep just before working out, so she sleeps through
Color says sport blue, but it is purple, not blue. Since I don't plan on wearing it uncovered, color isn't a big deal, but it is purple, not blue.

Overall, I prefer this to the Fiona, and I think it might just be the perfect running bra for ME!
