I like the idea but the problems:
-awkward closing! zipper requires two hands but you are likely to have the cups of the pump fall out or slip around while zipping
-size range XS-medium?? got to be kidding. it's very picky trying to get the width of the back and front so that your nipples fall right in the center of the front nipple openings. and if they're off to the side the cups of the pump slide and nipples rub the insides during pumping-- OUCH!
-not worth the price
-not a bra I'd want to wear all day and getting it on and off also not convenient.
