GroVia O.N.E. Diaper

22 reviews

A nighttime diaper answer for many families.

Stock Status: In stock as listed. 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 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.

Great overnight diaper!

After four kids I was still looking for a cloth overnight solution. I’ve tried the big and bulky. I’ve tried a bunch of added items to stay dry or boost absorbency. I even tried wool with this kiddo and another brand’s fitted underneath. Nothing has worked for us so we quit trying and go back to disposables for overnight like we have done with every other kiddo. A friend told me about Grovia O.N.E. I was like this is my last kid I’m not buying any more diapers. And then COVID-19 happened and I couldn’t get my hands on any of our disposable overnight diapers anymore. Fine I’ll try GroVia ONES for overnight. They are perfect! Seriously. Our “baby” is 20mo and a little over 20lbs. She’s a flooder. Meaning she can out pee a lot of diapers because she pees a lot all at once. These diapers can handle her all night long. I use both the inserts it came with and she’s dry and hasn’t wicked any moisture into her PJs all night long. And it’s stay dry fabric on the inserts so she’s not waking up due to feeling wet. We now have 6 of them three to use and three in the wash. I would highly recommend them. Also I’d be interested to know if Green Mountain has any interest in carrying “GroVia big ONE” at any point made for toddlers and older kids who aren’t dry overnight. If so I would be interested as “baby” gets older

This is a great diaper

We use these as overnight diapers. We never get leaks! I haven’t had any stink issues yet, which I thought would be the case, because of the rather thick inserts. This diaper will fit my 20 pound 4 month old probably longer than any other diaper I own. The fit is great!
