This is less like a bra than a 1/2 lined tank top with an opaque and tighter fabric for the 'bra' part. It does support and is good for running, but mostly because you are being flattened up top. That's fine because you aren't flopping all over if you are running. It's also comfortable to wear around the house. I wish there was more belly support. With the top flattening, if you have a little bit of belly, you look straight up and down from the side. But worth buying for the comfort factor.
