The New FuzziBunz One-Size Cloth Diapers

In the 4 1/2 years I’ve been cloth diapering my boys I’ve tried a lot of different brands and styles of diapers.  But, up until a month ago I had never tried a FuzziBunz diaper.  Last month FuzziBunz sent me a couple of their new one-size diapers to try out.

This year FuzziBunz has redesigned their popular one-size diaper.  Working from the ground up, Roy Couvillion, structural engineer and grandpa of 9, has redesigned the new FuzziBunz one size diaper from the ground up.

Here are some of the features you’ll see on the new FuzziBunz one size diapers…

Having a skinny baby or toddler in cloth diapers can mean leg leaks, super bulky bums, and just poor fit in general.  As a momma of a skinny baby, I really appreciate that FuzziBunz has taken into consideration that babies and toddlers come in different sizes.

It was that very fact that prompted FuzziBunz to create not ONE but TWO sizes for their new One-Size diaper!

  • The One Size – Small fits comfortably on children from 7-lb infants to 30-lb toddlers
  • The One Size – Large fits comfortably on children from 10-lb infants to 45-lb toddlers

The two different sizes give parents a choice of fit depending on their child’s specific body type. The OS – Large has a wider crotch and a much larger insert. The OS – Large can also be used for late potty learners, nighttime bed wetting, or special needs children.

Let’s take a look at the One Size – Large…

Keep in mind that my 20 month old is in the 60th percentile for height and in the 25th for weight.  So he’s fairly lean little guy.

My skinny man is obviously not the body build the diaper was intended for.  The diaper is bulky in the back and tended to flip forward under his belly.  That, however, had no impact on the diaper’s effectiveness.  I am completely satisfied with the absorbency and we never had any leaks.  I’ll continue to use this diaper as a regular part of my stash!

Now let’s take a look at the One Size – Small….

Now that fit is more like it! Super trim in the bum and crotch area.

My only complaint is that the insert on the OS – Small is a little too small. And, by that I mean too small to be absorbent enough for a toddler’s needs.  Okay, so if you have an average pee’er the insert is going to last you 1 1/2 to 2 hours–not bad–but it is totally inadequate for the floodgates that open at a toddler’s naptime.  The proof of which lay in my little guy’s wet sheets–the only diaper he has ever soaked through at naptime.

For this diaper I’ll probably be adding an extra bamboo insert on top of the microfiber insert. It would be pretty cool if the size Small insert had one more layer of microfiber to compensate for its smaller surface area.

Here is a closer look at the size Large and Small contoured inserts…

That’s a big difference!

Overall, there are so many features about the new FuzziBunz One Size diapers that I LOVE!

  • I love that you can choose sizes based upon the build of your child.
  • I love the wide leg and back elastic.
  • I love the ability to customize the fit with the button hole elastic.
  • The button hole elastic will also make for easy elastic replacement later on.
  • I love the perfect fit of the size Small on my lean boy.
  • I love the absorbency of the size Large insert.

  1. When my baby was in diapers I loved turning to cloth, for me it was a better way and I love the whole eco friendly thing about them. They are also more better at adjusting.

    These look like nice diapers to use. I have never used cloth diapers before. It's nice that they redesigned these.
