I've bought a couple and find them comfortable enough - but I'd have to agree, it doesn't bind as flat as I would like but the convenience of having the zipper and hooks is indispensable to me.
BTW - Their 14 day return/exchange policy sucks. I've gotten stuck with two that don't fit and I can't exchange them for one that works out. If you choose to order, make sure you order the correct size and make sure you follow their return/exchange policy to the t! (even the whole, Shower before hand piece.)
