The cups seem to run a bit small and, though I didn't need to yank on the band to fasten it, the hook and eye closure didn't hold up to even 1 wear of a light workout.  It's not a bad bra; I'd consider it medium impact at most but I wear a GG cup so finding that kind of control is a pain. If I'd paid more for it, I'd be furious; as is, I'm more annoyed at the quality control.  I wouldn't buy it again, but it'll tide me over until I buy a new one.
