Thirsties Duo Fab Fitted Review & Comparison To Fab Fitted Diaper

thirsties newborn fitted vs duo sz 1 ftted

I have done a Thirsties Duo Diaper Review and a Thirsties Duo Wrap Review, so I was curious about the new Duo Fab Fitteds.  I was super lucky and I won a duo fitted and cover in a Dirties on Diapering backer giveaway!  I wanted to do a comparison to the discontinued sized fab fitted, but I didn’t have one, and I was having trouble finding one.
I emailed Thirsties hoping they had one stashed in a warehouse they could sell me, but no such luck.  Their customer service is so awesome that without my asking, they posted on their Facebook page asking if any of their retailers had them in stock.  I found what I was looking for at Fern Leaf Boutique thanks to their help.  I ordered on Monday, February 28th and even though FLB is in California (I’m in Maryland), the diaper was in my mailbox on Wednesday March 2nd!  Whoa!!

I bought the fab fitted in the extra-small/newborn size.  Fitteds and covers aren’t my first choice, but they are fantastic for holding in the explosive newborn messes.  I don’t have a newborn but hey…don’t judge me.  I love cloth diapers!



The discontinued fab fitteds are sized.  X-Small fits 6-12 lbs, Small fits 12-18 lbs, Medium fits 18-28 lbs and Large fits 28-40 lbs. 


They have a super soft outer, hook & loop closures and laundry tabs.

The fab fitteds have a sewn in microfiber soaker and stay dry inner.

Here is the X-Small measured folded and stretched:

Since I don’t have a newborn, I am using my usual “model.”  I’ve also pictured him in newborn and size 1 disposables, so you can compare.

The retail price of the Fab Fitted was $14.50, though I got mine for $10.95 and free shipping (yippee!!) since it was discontinued.

The Duo Fab Fitteds have a lot of the same great features, with a few improvements.  The MSRP is a bit higher at $17.00, but they are still a great deal when you consider that you are replacing 4 sized diapers with a size 1 and size 2 duo diaper.

The duo fitted comes in easy hook & loop closures with laundry tabs, or snaps.


It still has the same soft, stay dry inner lining.


The microfiber soaker is sewn in a tunnel design for more thorough washing, quicker drying time and the ability to stuff it further if needed.

Of course, the duo fab fitted has rise snaps to adjust the size of the diaper.  Like the other duo products, the size 1 is estimated to fit 6-18 lbs and the 2 fits 18-40 lbs.

If you wonder about sizing, my Duo Wrap Review has a photo of my son at 21 lbs in the size 2 on the smallest setting, and the size 1 on the largest setting taken the same day.
Here’s the small setting of the size 1 measured folded and stretched:

So to recap the differences, of course the sizing difference.

Small setting of the size 1 duo is about the same size as the x-small fab fitted.

So, same great features, but now with the duo rise snaps (which don’t seem to add the bulk, probably largely because the soaker doesn’t fold/bunch on smaller settings.)  It’s available with a snap closure, and has an improved soaker style, and $2.50 higher price tag. See this on my newborn.

    […] In nearly 2 1/2 years of cloth diapering, I have purchased and reviewed lots of Thirsties products including a size 2 duo diaper I bought about 20 months ago. However, as I was getting ready to post my Thirsties Duo AIO review, I realized I’ve never really done a proper duo diaper review. My June 2010 review was really before I did my reviews the way I do now, and while I photogrphed and mentioned the size 1 in my newborn cloth diaper post, I didn’t go into a ton of detail, and I’ve never compared size 1 to size 2. Not even in my duo wrap review or my duo fitted review! […]
