When making this diaper, GroVia thought of almost everything. We found the O.N.E. to be a diaper with superb quality, excellent absorbency, 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 just got more absorbent with each use. This diaper, although bulky, can manage messes from even the heaviest of wetters. We recommend it to parents that are looking for a solution for babies that usually leak through their diapers, or for overnight use.
GroVia O.N.E. Review
Pros: Easy to use, good absorbency, durable
Cons: Long dry time, needs lots of prep
Our Analysis and Test Results
In 2009, Kim Ormsby launched a diapering line called GroVia, with a mission to provide products that are high-quality, eco-friendly, as well as a wallet-friendly to families around the world.
When it comes to absorbency, this diaper lives up to the hype. The GroVia O.N.E. scored near the top of the group 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 take anything you throw at it.
We like the GroVia O.N.E. for its incredible absorbency capabilities, which is why 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 on liquid. There is a soft microfleece lining covering all of the absorbent fabrics and acting as a wicking agent to keep 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 of the others in our review, keeping them in place, so you don't have to worry about traveling inserts. The placement of each 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.
Although it only has a single row of waist snaps, we felt that we were still able to 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 having to send the entire diaper to a snap conversion program.
The GroVia advertises the O.N.E. as an all-in-one diaper; however, there's a little more to it than that. The diaper cannot be used without the snap-in inserts, making it more of a mix between and AOI and AO2. It does take two steps to get ready for 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 when considering its remarkable absorbency, it is not so surprising. It was large enough to make it somewhat tricky to dress 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.
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 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.
