I must say although some of the reviews here speak ill of this bra I have no probs with it. First of all it's a sports bra, not a Victoria's Secret push-up....boob separation is not necessary, when it's supposed to be combating jiggle. It does however come with molded cups and no underwire and it still isn't uncomfortable to me

Pros:
-The bra band fits snug enough and does not bite.
-Even with a cup size down the bra is not tight. I can breathe properly without the feeling of suffocation
-Adjustable straps (these are a heaven sent). Adjusting too tight will cause the straps to dig into the shoulder.
-No underwire and the girls stay in place.
-Overall it's really comfortable. I jumped up and down like rabbit and had no problems at all
-Back closure...need I say more
-Wider strap placement. Let's face it, if you have big boobs racer back styles do not cut it where support is concerned. Because these straps are placed more like those on a regular bra they offer more support.

Con:
-There is still some amount of jiggle, not too much to be uncomfortable though.
-Doesn't wick sweat away easily..prepare to stay wet

The Fiona is similar but offers more compression and no jiggle /much less jiggle than with the Helena.
