This is a nice bra, however I do not wear as sports bra. I use it as my everyday bra as I need a lot of support. Plus, I like when bras make my breasts look smaller and this one does.
The only problem with it is that the straps keep falling down, which is really annoying!
I have the Shock Absorber Women's Run Sports Bra which works much better for when I am running although I also think this one offers a good support.
Overall if you don't mind pulling your straps up, this is a very good quality bra.
