Thirsties Diapers One Size Cloth Diaper Options

If you are planning to cloth diaper your baby to save money over disposables, you’ll want to check out the one size options from Thirsties Diapers that can be sized to fit your baby as they grow.

If you cloth diaper (or are at least researching cloth diapers), I’m sure you’ve come across Thirsties diapers.  When I began my cloth diapering journey, I read so many recommendations for this relatively small company.

They make quite a few different cloth diaper types including one size cloth diapers, Duo Wrap diaper covers, prefolds, fitteds. they also make cloth diaper accessories including cloth wipes, cloth diaper inserts, and pail liners.

Most parents who decide to cloth diaper do so for 1 of 2 reasons [or maybe a combination of both like me] – to either save money or to have a more natural option for their baby and the environment.

If one of your reasons is to save money, you might be leaning more towards one size cloth diaper options so you don’t need to buy so many different types and sizes of diapers for your baby throughout their cloth diapering journey.

In my opinion, there’s only one single drawback of one size diapers and that’s using them when your baby is a newborn. They can be quite bulky on newborns, but once your baby is about 3-4 months old, most one size diapers will fit them just fine.

One exception to this is Softbums diapers. I’ve found that even their one size cloth diapers fit wonderfully on newborns.

Thirsties diapers now has great one size options also including the Natural One Size Fitted, that needs to be used with a Thirsties Duo Wrap to be waterproof, and the Natural One Size All in One from Thirsties Diapers.

  • Absorbent interior consists of 11 thirsty layers of natural fibers : 3 layers of organic cotton in the body and 2 soaker pads with 8 layers of hemp/organic cotton.
  • One size diaper provides a customizable fit for most babies from birth to potty.
  • Convenient, trim fitting and absorbent. Goes on in one simple step – cloth diapering doesn’t get easier.
  • Gentle elastic around legs and waist provide protection against leak.

We have used a variety of Thirsties diapers and covers (and loved them!) when Sophia was a newborn, so I was excited to get the chance to review a Duo Diaper*.

I chose the print, Blackbird, because it so just so unique and cute, as are all the Thirsties print/color choices!  The fit of this diaper is so comparable to the Thirsties covers.

I love the fact that they have 2 OS choices, so that they will actually fit a newborn AND a 2 year old without so much bulk and tightness. This system may be a bit more expensive than a regular One-Size system (like Bumgenius or Rumparooz) because you are buying two sizes, but they really fit each size much better and it’s still much cheaper than buying disposables.

Thirsties Duo Diaper

Why I Love the Duo Diaper:  I love this diaper for 2 main reasons… I love the fit.  It will truly grow with Sophia (she is on the smallest setting of the size 2) and the leg gussets really keep everything in the diaper, without being too tight on her chubby, cute legs!

I also love the fact that the it has a “sleeve” design, meaning you can stuff from the front or the back, which makes it possible for the machine to “agitate out” the insert… no pulling out yucky, soaked inserts!!!
