Our bestselling prefold cloth diapers in attractively packaged six packs. Back side of packaging comes with dual language use and washing instructions (English and Spanish). Comes in two sizes and two material types. Size 1 is the Infant 4x8x4 that fit 7-15 lbs. Size 2 is the Premium 4x8x4 that fit 15-30 lbs. The first material is the bleached white 100% cotton gauze weave. The second is the unbleached natural ivory color and is also a 100% cotton gauze weave. The unbleached must be washed prior to use 2-4 times for absorbency while the bleached requires just one prewash. The unbleached has been the better seller due to its attractive natural color in contrast to many other products on the market. Prefold diapers require a diaper cover for waterproofing and we recommend our OsoCozy One Size Diaper Covers to go with these prefold cloth diapers.
