3 reviews

 GroVia O.N.E with Buttah velour soft outer fabric.

Stock Status: In stock as listed. Usually ships in 24 hours.

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.

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

Soft, squishy, very fluffy. Has some Cons

I have had a love hate relationship with the Grovia ONE over the years.. Pros for this specific style : The Buttah diapers are SO soft, and squishy. I love the outside material and the stay dry on the inside is very ideal for my kiddos. I don’t use many PUL diapers at all as we use wool and fitteds primarily , I’m happy they decided to come out with this soft style. Absorbency comments : the absorbency is fine on these diapers for most kiddos. We have used for overnight on a super soaker and now my daughter who is not as heavy of a wetter overnight - had to add a doubler for the firs kiddo and still got some leaks.. for my daughter I use 2 inserts and sometimes a thin hemp Doubler and it works plenty for overnight.. so absorbency wise it CAN work if you play around with addons. We prefer this as a going out of the house/long car rides diaper though. Here’s why.. my cons below .. Cons with the ONEs : the stink, no matter what there is no way around it. These diapers hold in stink like none other with the microfiber in the shell and the stay dry fleece, they are just way harder to clean. Always stink the worst in the mornings, worse than any other diaper (and those smell too after 12 hours, so that’s saying something.) Also this diaper is very very fluffy. Its inserts are made of cotton with stay dry fleece, to get all the absorbency needed for cotton, you need a lot of layers so don’t expect this to be trim especially when using both inserts. The fit can be a bit awkward to figure out (the top waist part always flips outward) And I dislike the Velcro addon. Personally it’s just extra pieces that can get lost. Would I recommend this diaper ? The Buttah specifically yes & no .. it’s a tough call. I have them, we use them, I wouldn’t buy anymore but they can work if you take into account all pros and cons, it’s worth a try. Just don’t buy an entire stash of them. I prefer other diapers.

This Diaper Works.

I have not experienced any leaks with this diaper. I am giving it 3 stars because it does not fit my 16 pound baby. In order for the legs to be tight enough, I have to have it snapped so that the outer snap on one side does not have a place to snap into. I was also looking forward to the softness of this diaper, but after only the prep wash it was pilling quite a lot.

Surprisingly disappointed.

I purchased this diaper to try as I've read over and over that it's the best overnight diaper for heavy wetters.... Well. Not so much. Our 4 month old foster-baby has consistently and *completely* soaked through this every night we've used it. More so even than a workhorse with extra insets. The only "solution" we've found for not soaking through (and even then, some nights he still does) is a double-stuffed Rumparooz pocket diaper. I'm at a bit of a loss. That issue aside, the diaper is well made. My husband loves the hook and loop option- I'm not a fan of how it detaches...I get that it's for longevity with washing, etc. and that you can buy replacements, but I just envision lost pieces. The diaper is soft and cozy and cute. My issue is just with the lack of absorbency. It is SO bad that it goes against every other review I've read. This makes me think I may have just ended up with a dud, because it just doesn't make sense with what *everyone* else has said. I do like the idea of the snap in inserts and the softness inside and out... I really want to like these, but I've very disappointed with the absorbency. I like to reserve AIO's/AI2's for overnights and out and about...but I can't trust this for either of those.
