GroVia O.N.E. Cloth Diaper Review

Here is a truly one-of-a-kind cloth diaper: the GroVia O.N.E.

Outlast closure, No prep, Easy to use. Though not exactly easy to remember, that is what the O-N-E stands for in this diaper's name.

I am going to be super, super candid in saying that I had no interest in ever trying this diaper. I bought it and tested it with an extreme amount of skepticism.

Why was I skeptical? My impression of the ONE, as a spectator, was that this diaper was bulky, and made up of microfiber, which I am not a fan of.

Turns out, I actually knew very little about this diaper.
When I read about it, and then eventually bought it, I was pretty shocked by how many features it actually has.
This has to be hands-down, the most unique diaper I have ever seen on the market.

The GroVia O.N.E. is a one-size (fits from approximately 10-35lbs), all-in-one diaper.

My first shocker came when I realized that it is not just a microfiber diaper. Though it has a microfiber core, the bulk of the absorbency is actually made up of cotton.

You know cotton, my absolute favorite textile- cloth diapers or not.

The cotton in this diaper requires no prepping.
It only needs one initial wash, then it is ready to go.

The absorbency is made up of two soakers- one small, and one large.
They are attached in the back of the diaper with a single snap, depending which size or amount of absorbency you need.
Use the small soaker for lower rise settings and less aborbency, the large for higher rise settings and more absorbency, and both together when you need a lot of absorbency.

The inside is lined with a stay-dry microfleece.

The really unique feature on this diaper is ability to switch between hook and loop and snap closures, thanks to removable hook and loop strips.

It retails for $22.95.

What I Like:
This diaper is absorbent.
Even with just the single, large insert, it's a pretty thirsty diaper.
My two-year-old was the first to get this one on the bum, and when I changed him, it was SO heavy with pee. I was impressed it had held all that without leaking.

A lot of people swear by this as an overnight diaper, with both soakers. My boys don't pee as much at night anymore, so I don't know if I am the best testimony to that right now. My biggest concern around this as a nighttime diaper is the microfiber core holding stink over time from being used with such concentrated pees. When my baby grows up, I'll have to try it for awhile and report back.

If you follow me on Instagram, you know that I have three in diapers right now.
This fits both my toddlers very well.
It is quite bulky on my four-month-old, but a lot of one-size diapers still are.

It is not as trim as my diaper of choice, but it definitely isn't as bulky as I had imagined, unless both inserts are in it.

The price point is fair, especially for it's versatility.

What I Don't Like:
My biggest complaint about the ONE is honestly the packaging.
The custom plastic packaging is just excessive to me. It's not something that could be recycled- or really reused, like the generic plastic bags can.
 I couldn't imagine buying a whole bundle of these diapers at once and getting dumped with all this extra packaging. It's a huge deterrent for me, personally.

My least favorite thing about the diaper itself is the way it snaps in.
It technically should qualify as an all-in-two, since the soaker unsnaps every.single.time. you wash it, and you have to chase it down to snap back in while folding.

I also have this thing with soakers that attach in the back, because I always feel like poop is going to get trapped behind them during spraying OR the soaker ends up dropping down into the poopy toilet water.

In time, I've come to not mind a little fluff, but I still wouldn't use this full-time, due to the bulk. There are all-in-ones out there that fit my kids much more trimly, especially my baby.

I could just as well throw the hook and loop conversion straps in the trash, since I'm not a fan of that kind closure, but the fact that they are supposed to be removed for washing is a bit of a bummer for me. I don't even remember to fasten hook and loop fasteners onto their stay tabs to wash them, so I couldn't imagine ever removing the entire fastener. But maybe that's just me.

I'm laundry lazy.

I know this is totally personal preference, but I don't like microfleece linings.
I prefer natural fibers against the bottom, plus it always just starts to look pilly and sad after a few washes.


I will be buying this diaper again. I like it. It's absorbent, and is mostly natural fibers. It's a diaper I can trust to get us through a grocery trip, or church, without leaking.

I recommend trying it if you are a GroVia fan, or looking for a diaper with good absorbency.
And I HIGHLY recommend buying it in Basil, one of my favorite diaper solids, ever.

I own a Basil Hybrid, but I think a ONE will be heading my way soon, too!
