GroVia O.N.E. Diaper

26 reviews

A nighttime cloth diaper answer for many families.

Stock Status: In stock. Usually ships same or next business day.


The O.N.E diaper is a true all-in-one diaper (fits 10-35+ pounds) that comes with everything you’ll ever need to cloth diaper a baby: enough absorbency to forget boosters and doublers (even overnight), two built-in closure options, and a heavy-duty construction that is built to last.

The O.N.E. features a unique Outlast closure system that gives the user the ability to choose between Hook & Loop and Snap closures, and the ability to buy a replacement kit when your Hook & Loop wears out. O.N.E's absorbency comes from a hidden body layer PLUS our one-of-a-kind cotton, channeled soaker design that is trim yet absorbent. All with the same amazing quality you've come to know and love in GroVia products.

 No need to choose between Hook & Loop or Snap closures

With the O.N.E., you can have both! The removable Hook & Loop closure is perfect for those who love a “no-hassle” fit but want to transition to a snap closure later on.

  • Built-in extra absorbency means the perfect nighttime solution

  • No prepping - can start using right away
  • Modular Snap In Soaker System allows for customization (includes both large and small insert)

Great for nighttime

This has wonderful absorption that makes it a great nighttime solution. It is very soft and comfortable because of the micro fleece (it doesn’t leave sock marks on my baby). Also nice for daytime because you can snap out the larger soaker and just have the small one. My only con is that there is no option to have cotton on the baby’s skin. Some babies are sensitive to synthetic materials so this would be a nice added touch! All in all I really like this diaper and would recommend it if you’re struggling for a leak proof night diaper. :)

This is all we use for nighttime now. With a small hemp doubler added ,this diaper keeps our 20 month heavy wetter,dry all night. It’s also much less bulky then anything else that we have tried. It’s nice that it has the Velcro option though, once I figured out the setting for the snaps I only use the snaps. Grovia has a good video on their site that is helpful too. The absorbency really improves after 6-8 washes. Highly recommend as a less bulky nighttime solution.

Great diaper

I bought this to use for nighttime. I put a cloth doubler under the insert for extra absorption and it works great for a 17 month old after sleeping all night the diaper is really soaked and baby feels dry. This diaper would be bulky for daytime but for nighttime it is trimmer than a prefold with 2 doublers. It does take at least 6 washes to become really absorbent though. She is using the middle rise now . I think that when she gets bigger the stay dry large hour glass doubler will work well too for nighttime in the o.n.e.

Great diaper!

This diaper has great absorbency. I used it as an overnight diaper for my 14 month old who still nurses from 2 to 3 times during the night and is a heavy wetter. The diaper absorbed all the urine and baby woke up dry and without leaks. I love that it has the snap and hook and loop option. The only thing I do not like too much is that is very bulky and the colors, they could be a little brighter but that's just me, I like bright colors. Other than that, great absorbency as a 12+ hr. overnight diaper.
