I didn't use them overnight - I had a pocket and it was good, but I didn't feel secure enough to go overnight. Anyway at that time I was solely doing fitteds with wool covers for overnight (far more reliable and still my favorite choice for nighttime).
I had a sized pocket and she has outgrown it, and I am on a CD-shopping hiatus hence not having current information.
good to know! My husband diapers her at night and says no fitteds, so I'm on a search for a good pocket overnight dipe that's not a bumgenius - LOL!
her prices were so good I thought I'd ask!
