Hip Heinys Flannel Pocket Fitteds --- Matching flannel prints for inner and outer. Each Pocket Fitted comes w/ one microterry stuffer. Lastin is used for elastic...strong elastic to endure washings and dryings. This is a one size fitted diaper which, needs a cover for waterproofing. Best fit is with a diaper pin...just one pin will do per diaper. I can add snaps or velcro but, you won't get a good adjustable fit. Goes really well with the Hip Heiny Bamboo Fleece longie or shortie. :0)
