I just got the mango one. The 'air vent' model.
It binds about as well as the underworks double-front. BUT, I can get it on without a struggle, and it is comfortable and breathes and isn't instantly sweaty. More comfortable, in fact than the various compression sports bras, and looks better too. It's so comfortable that I wonder if a smaller size might bind better and still be wearable. Alas, it doesn't do the dream thing, which would be to allow me to wear it as a tank-shirt and still look flat, but under a shirt it looks perfect. And its shoulders are wide enough apart that it doesn't show under a t-shirt, and it doesn't roll up and annoy the heck out of me.
Only drawback is that the thing is absurdly overpriced, the mango people provide a sizing chart and then tell you to order a size bigger anyway, and also tell you you can't return it if you get the wrong size, a situation that made me want to kick somebody in the teeth.
