Product Details
Happy Heinys One Size Pocket Diapers feature a snap setting that allows the diaper to expand from small, to medium and then to large as well as a cross over tab that gives the diaper a perfect fit. This diaper also comes with two microfiber inserts, one small and one large to provide a complete diapering solution.
These diapers share some of the features of the original sized Happy Heiny's diapers. They still feature custom milled fleece and no leg casings. This allows these diapers to contain messes without leaving any red marks on your child's legs. It is often asked if the fleece should roll out? The answer is yes! Do not try to roll the fleece in. This will cause wicking if you try this. They are made to have the fleece roll out so the only thing that touches your child's delicate skin is the soft fleece.
Happy Heinys has worked hard to earn the trust of thousands of families with their original sized pocket diapers. We are thrilled to bring you that same quality and measure of success with our one size pocket diapers, available in both aplix or snap closure. Happy Heinys one size pocket diapers use only the best materials, from the custom milled fleece to industrial strength notions, to create a diaper that will fit your baby from about 8-35 pounds. With 4 sizing options, easily accessible on the front of the diaper by using durable snaps, we can offer a precise fit for your baby's growth stages. Our adorable prints have been made to the same specifications as our popular sized diapers, which means they are not going to wick urine during nap time or nighttime use.

With your one size pocket diaper purchase, you will receive a set of two microfiber inserts, which are 3 layers each. The smaller insert may be used on the smallest setting of the size range on the diaper. The larger will fit the medium and large settings, to which you can add the smaller insert for extra "wet zone" protection of 6 total layers of thirsty microfiber! The unique design of our diapers allows for additional stuffing if needed. A hemp Stuffins provides an absorbent boost when paired with the included microfiber inserts. Stuffins fill the width of your one size diaper, and also inch for inch absorb a great deal of moisture for those times when a diaper needs to last. Place a thirsty microfiber insert on top of the stuffin, all inside the one size pocket for naptime or nighttime to complete a system that compliments both fit and function.
