This post was originally published September 18, 2017. It was updated February 2020. I purchased this diaper myself from the second release of the Best Bottom AIO (first release was a slightly different cut). This post does contain affiliate links to cloth diaper shops I work with.

Best Bottom designs some of my favourite prints. Month after month, I’m always smitten and Miss Piggy is definitely a contender for my favourite Best Bottom Print. And yes, it still is in 2020. 

Best Bottom released a new AIO diaper earlier this year. It brought much excitement to the community. Finally, maybe, something that will stand up to heavy wetters everywhere? Truthfully, a little confused on why a brand would make a heavy wetter diaper and AIO – these two things are not usually in the same sentence. But, hey, here we are.

Check out my first impressions of this diaper. At first, I felt blah about the Best Bottom AIO diaper. It wasn’t anything special, but over time this has become a diaper that I enjoy because of it’s fit and function.

About the Best Bottom Heavy Wetter AIO

The Best Bottom Heavy Wetter AIO is sized like the Best Bottom Bigger diapers. To check out how those compare to the standard one size, visit this review/comparison. That means this diaper is ideal for kids 10-40+ pounds.

The Best Bottom AIO diaper features a single snap wings with a 3×4 rise setting. It has a cross over rise setting and is very adjustable for babes from birth to potty training (and beyond.

Inside the diaper, you’ll find double leg gussets and TWO layers of bamboo viscose lining the mid section of the diaper. This is complimented with a 6 layer, one size, bamboo viscose insert topped with a no-pill fleece topper.

The insert features double snaps that snap to the back of the diaper, and a single snap at the front. A third snap is found just under the back snaps. This snap allows you to match other inserts to this diaper for additional absorbency. The double gusset designs allows you to bulk this diaper while still offering an incredible fit for babies of all sizes.

The diaper is made in the United States, and available at many retailers including Lagoon Baby in Canada and Nicki’s Diapers in the United States. Or check out my list of affiliate shops to find a retailer closer to you.

5 Reasons you might LOVE the Best Bottom Heavy Wetter AIO

1. If you LOVE the Best Bottom Fit.
   Best Bottom Fans will love the fit of the Best Bottom Heavy Wetter AIO. This cloth diaper has the fit and style of the classic Best Bottom shells. I know Mama Banana’s Adventures fussed a bit with the fit and wasn’t super impressed but I haven’t had the same struggles.
2. If you’re looking for a BIGGER fit.
   What the one hang up is the Best Bottom AIO is bigger than the standard OS Best Bottom shell. This gives users a bigger fit that will hopefully last you thru potty training. This bigger shell also lets you have more room to hold all this absorbency.
3. If you want an ADJUSTABLE and CUSTOMIZABLE AIO Cloth Diaper.
   The Best Bottom Heavy Wetter AIO is adjustable and customizable. This makes it a functional diaper for all your needs. It comes with a standard six layers of the bamboo insert, but additional inside snaps make room to snap in your favourite Best Bottom inserts for extra absorbency.
   
4. If you want Stay Dry.
   This is one of very few bamboo-based all-in-one cloth diapers that offers a stay dry liner (the other is the Lighthouse Kids OS AIO Cloth Diaper). 
5. If you want awesome Daytime absorbency.
   While it is called the Best Bottom Heavy Wetter AIO, I wouldn’t classify this as a night time diaper. It is a heavy wetter diaper for daytime absorbency. In my kitchen, the absorbency of this diaper is on par to more absorbent AIO like the bumgenius Elemental and Simplex. However, this is not enough absorbency for many heavy wetting nap babies and bedtime. If you wanted to use this at bed or nap, simply snapping in an additional insert would get the job done.

 

Things I don’t like about the Best Bottom Heavy Wetter AIO

I found that mine was susceptible to wear. These wear patches along the seams of the two layers of sewn in absorbency appeared right away. However, despite this being in regular circulation, this diaper didn’t break down further.

I also hated that the Best Bottom Heavy Wetter is classified as an AIO but you have to attach an insert. I classify it as a snap-in style AIO diaper, or a not-AIO diaper. This is just a fancier version of their covers/shells. I don’t think it’ll offer you more than what your shell system can offer. My inserts always unsnapp and I have to pair them up every time.

Buy it?

Yes, maybe. I do love the Best Bottom Heavy Wetter as a reliable daytime absorbency when I need most. The price tag scares me off. If you can afford it, and it works for your lifestyle, I recommend this AIO diaper if you are okay with snapping inserts when they separate in the wash.
