Happy Heiny's One Size pocket diaper covers are made from an inner layer of high quality, lightweight 100% breathable custom milled fleece and an outer layer of stretchable polyester with a polyurethane laminate.



The two layers form a pocket to place a the two included three layer microterry inserts or other pocket stuffings into.

Happy Heiny's One Size diaper has three columns of four snaps to adjust the rise on your diaper. This will give you a total of 4 different sizes in one diaper. You don't have to unsnap the diaper to wash. Just leave it snapped up until you need a larger size. The snaps allow the diaper to fit most babies from about 8 lbs- 35 lbs. An investment that will save you money throughout your diapering time.

Our one size diapers also come with 2 thick and fluffy micro fiber inserts. One small and one large insert. You may use either 1 insert or both or more as needed depending on how heavy your little one wets.
