This bra is awesome.  It adjusts in the straps to give you just the amount of support you want depending on the level of activity .  I use it to run and it's very tight and keeps me in place.  It has 4(!) hooks with three settings of hooks.  Before I got this bra, I was using two Champion bras from Target and still wasn't achieving this level of support and lack of movement.

My only complaint about this bra- and this is why I would give it 4 1/2 stars instead of 5- is there is a spot on the straps that kind of irritates my shoulders, but after 8 or 9 miles, I can't imagine any bra that gives more support for those 8 or 9 miles, so I'm going to try a little bodyglide and keep on running.
