The GroVia O.N.E. was a diaper that GroVia fans had to work for! It was launched on Kickstarter in fall 2014, closing with over $65,000 pledged by over one thousand backers. Even I joined in the fun, pledging $20 and getting a cute T-shirt for Cub. I reviewed the O.N.E. when it first launched and Cub was two-and-a-half. The design has changed slightly since then, but its popularity has continued to soar, so I thought I’d review it again on Little Miss Cub!
The O.N.E. is very different from other one-size diapers on the market, both in its cut and its design features. It is often touted as a wonderful overnight solution, and I know many families that use it very successfully at night. Because a lot of you ask me about my heavy-wetter overnight recommendations, I will state off the bat that the O.N.E. doesn’t last for Little Miss overnight; she was saturated even through her woollies when we did a test drive. That said, with both inserts, the O.N.E. does pass the three-hour test during the day which is a very important standard here at the Den!
So let’s take a look at the O.N.E.:
The GroVia O.N.E. is an all-in-one diaper that comes with two snap-in inserts. The product description doesn’t specify how many layers of cotton are in each of the two inserts, but it feels like three layers in the large one and four layers in the small one. The shell has a hidden layer of microfibre and the cotton soakers are topped with fleece. The two soakers can be snapped to each other or used alone in the shell, depending on baby’s size and absorbency needs.
Like the GroVia Hybrid Shell, the O.N.E. has a single row of closure snaps. Each O.N.E. also comes with Velcro strips and tabs that snap onto the closure snaps, turning the O.N.E. into a Velcro diaper. You can purchase replacements strips of Velcro when it wears out, as Velcro is wont to do.
We are using the O.N.E. with the snaps. I am too lazy to remember to detach the Velcro strips at washing time like you’re supposed to, so snaps it is. With only a single row of snaps, it’s really not hard to get the hang of snapping this diaper up, but the Velcro option is a nice feature to help ease families used to disposables into the cloth world, or to get a more precise fit at the waist, especially on smaller babes.
The weight range for the O.N.E. is 10–35 lbs. I tried out our original O.N.E. on Little Miss a few times between 12–15 lbs. I really struggled with the O.N.E. when she was this size, and found myself fiddling and tugging to get a gap-free fit at the leg. I rarely reached for it.
Now that she is about 22 lbs and 32 inches tall, I no longer find it an awkward fit like I did when she was smaller. With both inserts, we are leak-free for three hours. She still wears the O.N.E. on the smallest rise setting, and at the tightest waist setting without crossing over.
I’m definitely satisfied with the absorbency of the GroVia O.N.E. for daytime use. Whenever I do not need to add anything extra to a diaper to get three hours of use, I consider that a win.
I’m less excited about the quantity of microfibre in the diaper for the $30.95 price. Microfibre has its pros and cons. At the top of the pro-list: it is a no-prep fibre. The O.N.E. is marketed as a no-prep diaper, meaning that you wash it once for hygienic reasons and then you can use it. Diapers with higher amounts of natural fibres (especially hemp, cotton and bamboo blends) need to be washed multiple times before they reach their maximum absorbency, and this can be a turn-off for some consumers. Microfibre also dries quickly, even if you air dry. I don’t love microfibre because it can be harder to clean and thus more prone to stink, and it’s also not a very eco-friendly textile.
The O.N.E. is also marketed as being easy to use. I would definitely agree that once the diaper fits well on your child, it’s very easy to use. There are no pockets to stuff and the single row of snaps is easy to understand. (When you’re new to cloth, a double row of snaps and a hip snap can look really complicated!) The removable Velcro option is really neat, if you need it. It’s also marketed as a being “the perfect nighttime solution.” It would be amazing to find a diaper at this price that works overnight for us. (All the solutions we use are at least $50.) As I mentioned above, I do know families for whom this diaper works overnight. If you don’t have a heavy wetter, you could be in luck!
