Once I got myself strapped into this miracle of modern fibers, I was suitably impressed. The band didn't budge, the straps didn't slip, and although my breasts were flattened and unified, they weren't very bouncy, which is is impressive when we are talking about the kind of boobular momentum generated by a DDD. I wouldn't say it was perfectly comfy, but that's not my goal for a sports bra. The back straps took a little careful shifting to get right, and the band stayed put by virtue of being very snug. it was supportive, non-obtrusive, and well-ventilated.

Would buy again.
