yes they have the zipper, but I put all my pockets together once they are washed, so its just as easy as any other pocket. I like the zipper because its on the outside so there is never any poop leakage onto the inserts.
Kiwimama, the HH's have worked just fine for us, i've had them for over a year and they have been through alot and are still in great working order. They definately arn't as popular with peoploe as some of the other ones though and some people complain of leaks etc. But each to their own. I dont like bumgenius for those reasons, but other people love them.
