The Skinny

When making this cloth diaper, GroVia thought of almost everything. We found the O.N.E. to be a diaper with superb quality, excellent absorbency (eventually), and intuitive ease of use features. We were a bit nervous at first when performance was lower than expected but were happily surprised to find that it gets more absorbent with each use. This diaper, although bulky, can manage messes from even the heaviest of wetters. We recommend it to parents looking for a diaper solution for babies who often leak through their diapers or for overnight diapering needs.

Absorbency


When it comes to absorbency, this diaper lives up to the hype compared to the clothing diapering competition. The GroVia O.N.E. scored near the group's top in our absorbency tests.


The dual inserts work together to capture all liquids, and the soft microfleece lining repels moisture like nobody's business. Although it took a while to reach its maximum potential, we are confident that this diaper can handle anything you throw at it.

Likes


We like the GroVia O.N.E. for its incredible absorbency capabilities, so we recommend it for heavy wetters. With the dual cotton insert and an additional microfiber layer sewn into the cover, this diaper can hold an impressive amount of liquid. There is a soft microfleece lining covering all of the absorbent fabrics and acting as a wicking agent to keep the baby dry. In our lab tests, the GroVia came out near the top for absorbency, and when testing with a baby, the lining felt dry to the touch after changes.

We love that the two soakers snap into place, unlike many in our review, keeping them in place, so you don't have to worry about traveling inserts. The placement of the snaps makes it very intuitive to put this diaper together, andimpossible to do it wrong. This failsafe ensures that you will never put the wrong side of the insert against the baby's bum, even if you are changing in the dark.

The single row of snaps felt more secure than most diapers with this same feature.

Although it only has a single row of waist snaps. We felt that we could still get an excellent fit every time with this high-quality diaper. We also appreciate that it comes with a set of hook and loop closure tabs that snap on and off the cover. This way, you can have a diaper with infinite adjustments, and when they wear out, you can remove them and switch over to snaps or buy a replacement set rather than sending the entire diaper to a snap conversion program.

The GroVia has 3 levels of rise adjustments and 6 for the waist.

Dislikes


The GroVia advertises the O.N.E. as an all-in-one diaper; however, there's a little more to it. The diaper cannot be used without the snap-in inserts, making it more of a mix between an AOI and AO2. It does take two steps to get ready for a baby, but the inserts are still attached to the cover during use.

While in the end, we were very impressed with both absorbency and wicking capabilities, it did take longer than any other diaper to reach its maximum performance. Somewhere upwards of 9 washes! GroVia claims that this is a no-prep diaper, but when we used it after only a few washes, absorbency was only average. We feel that this emphasizes just how important it is to properly prep your diapers before using them.

The O.N.E. was one of the bulkiest diapers in the bunch, but it is not so surprising when considering its remarkable absorbency. It was large enough to make it somewhat tricky to dress a baby, so we tended to reach for dresses or other loose clothing when using this diaper. The bulkiness also means a longer dry time, but the inserts can be machine dried, so it is not as big of a deal.

Should You Buy the GroVia O.N.E.?


The GroVia O.N.E. is a diaper that reaches the upper limits of absorbency and is one we trust for its quality and durability. Although a little bulky, we feel that it is worth it, especially if you are struggling to find a diaper that will contain leaks. The soft lining keeps the baby comfortable and dry, and the features of this diaper make it easy for parents to use. Almost as easy as a true AOI. Even though it comes with a slightly higher price tag, we think that it will outlast other diapers and keep you satisfied with its top-notch performance.

What Other Cloth Diaper Should You Consider?


This diaper gets better over time, and that is why it performed well in our tests for overnight diapers. While it didn't impress compared to the other cloth options for day use, it might still be a contender. The Rumparooz Pocket is a great all-around diaper with impressive absorbency and adjustability with liners you stuff into a pocket. It offers double gussets for leak protection and is comfortable even if it is a little more involved for ease of use. If you have ease of use concerns, the bumGenius Freetime is the best choice for you, with a higher rank overall and better ease of use results than much of the competition.
