bumGenius 4.0 One Size Cloth Diapers - reusable, adjustable, sensible pocket diapers!

Jennifer Labit, the mastermind behind the bumGenius 4.0 One Size Cloth Diaper has mastered the art of listening to customers' requests.

The trim, one-size pocket diaper continues to be a favorite of cloth diapering families everywhere! With an outer fabric of soft, waterproof material, the bumGenius 4.0 One Size Cloth Diapers are now re-designed to accommodate even larger babies; a diaper that truly fits babies from birth through the potty training years.

An inner layer of non-pill, sueded, low pile fabric wicks moisture away from baby's skin to the absorbent microfiber inserts within. Keeping baby's skin dry helps parents avoid diaper rash or other irritations caused by prolonged exposure to moisture.

Inserts are tucked away to keep baby dry.

The microfiber inserts are tucked into the pocket and secured under a patent-pending flap - no more wet waistbands from inserts that slip up and out of the waist in back! A waterproof insert stopper prevents leaks at the tummy as well.

Stretchy casings rolled-out at the thigh and waist are a gentle way to contain messes without leaving red marks at the thighs. NEW REPLACEABLE ELASTIC is easily located when the pocket diaper is turned inside out. You can expect to use the bumGenius! 4.0 One Size Pocket Diapers for multiple babies; easily replacing the elastic when it loses its stretch.

Sleek and trim stretch-to-fit tabs.

The stretch-to-fit tabs render a more trim and customized fit; these non-wicking tabs stretch around baby's waist for a snug and comfortable fit. If you select "hook and loop" closures, expect an improved, grippier texture so tabs stay where they are placed.

To use: simply lay your baby atop the bumGenius 4.0 One Size pocket diaper and wrap the tabbed wings around baby's sides, securing them to the front panel.

bumGenius 4.0 are bundled with TWO Microfiber Inserts!

Pocket diapers grew quickly in popularity as the most absorbent cloth diapering system available on the market. Knowing the inserts make or break the level of absorbency, bumGenius! 4.0 One Size Cloth Diapers come with TWO of their thirsty Microfiber Inserts - one (1) newborn insert (also used as an overnight booster when your baby moves beyond the newborn size) and one (1) regular sized insert.

The redesign includes the same built-in, wider opening at the back waist; this can accommodate a man's hand to easily stuff or remove inserts from the pocket.

No worries about the wider slot opening at the waist causing leaks! As stated before, the bumGenius 4.0 One-Size Cloth Diapers patent-pending flap over the opening, keeps wetness completely way from your baby's skin.

bumGenius! 4.0 Cloth Diapering Made Easier!

Trim, Waterproof Insert Stopper

Because pocket diapers are stuffed for absorbency, many times the insert will shift to the front or the back, depending on the posture or sleeping style of the baby. When an insert pushes all the way up to the waistline, bunching at the front, moisture can wick into baby's clothing when the cloth diaper rolls outward. The manufacturer of the bumGenius! 4.0 One Size Cloth Diaper remedied this with an "insert stopper".

The waterproof "insert stopper" at the front waist disallows the microfiber inserts from pushing too far forward in the front. In addition, this feature helps the front pocket diaper area stay trim and flat, making it easier to fold down for newborns or smaller babies.

Love these!

I just received two of these diapers and can't wait to use them once my daughter arrives. The colors are adorable and the diaper itself is so well made. Can't wait to see how they hold up over time!

Great diaper!

I recently bought this diaper as part of the trial. My daughter is 14mo and 19 pounds, so, tall and skinny. We have had trouble finding diapers to fit her skinny legs but these fit her wonderfully, and have great absorbency without being too bulky. Love!

I'm new to cloth so I don't have too much experience with many brands, but after hearing such good reviews about this one I had to try it first. And I love them! They made transitioning to cloth so much easier!

Not very good quality. Wide in the crotch, horrible elastics. Wouldn't recommend.
