Thirsties duo diaper 1

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 photographed 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!

So the overview is that the duo sizing is size 1 for 6-18 lbs (0-9 months) and size 2 for 18-40 lbs (9-36 months.) This means that two sizes will fit newborn-potty vs needing newborn, one size, and potentially larger sizes once the o/s are outgrown. Both sizes of the duo diaper retail for $18.50 for solids and $19.50 for prints. There are 8 colors plus white, 5 prints, and the family tree print available exclusively at my affiliate, Kelly’s Closet. Thirsties products are made in the U.S.A., and the PUL is free of VOC’s, PVC, phthalates, lead, and latex.

Now the diapers are available in both snap and hook & loop closures.

Whether you choose size 1 or size 2, you still have 3 sizes to choose from via a snap down rise, as you often see on a one-size diaper. The overall fit is much like the duo wrap, and the duo diaper has the same double gussets.

The diaper has a microfleece, stay-dry inner, front and back pocket, and the insert agitates out without unstuffing. The insert is really two inserts that snap together; a 2-layer microfiber insert and a 5 layer hemp/cotton insert. I find that this combo is the 1-2 punch necessary for leak-free extended wear (car rides, naps etc.)

Here’s the smallest setting of the size 1 measured folded and stretched (you’ll find small/large size 2 measurements in my size 2 review):

Medium size 1 folded & stretched:

Thirsties duo diaper 15 medium Thirsties duo diaper 16 medium back
Thirsties duo diaper 17 medium side

Large size 1 folded & stretched:

Thirsties duo diaper 18 large folded Thirsties duo diaper 19 large stretched

Thirsties duo diaper 20 large Thirsties duo diaper 21 large back
Thirsties duo diaper 22 large side

Now here is the size 1 vs the size 2 (in blue):

Here I have both the size 1 and the size 2 on their smallest settings:

Thirsties duo diaper 23 small 1 vs small 2 Thirsties duo diaper 24 small 1 small 2
Thirsties duo diaper 25 small vs small Thirsties duo diaper 26 small vs small

Both on the large setting:

Thirsties duo diaper 27 large vs large Thirsties duo diaper 28 large vs large
Thirsties duo diaper 29 large vs large Thirsties duo diaper 30 large vs large

Finally, here is the largest setting of the size 1 compared to the smallest setting of the size 2:

Thirsties duo diaper 31 large 1 vs small 2 Thirsties duo diaper 32 large 1 small 2
Thirsties duo diaper 33 large 1 small 2 Thirsties duo diaper 34 large 1 small 2

Each comes with an insert sized to fit the diaper:

Here’s my 2 1/2 year old (ok, he’s “32 months” old if you want an exact #!) and about 29 pounds, in the largest setting of the size 2 (the small setting of the size 2 hit him around his belly button at a year old/17 lbs):

The small setting of the size 1 fit my little guy perfectly as soon as his cord stump fell off. It fit him with the stump too, but having diapers over it kept it from drying out. Here he is at 6 lb 5 oz and just a few days old:

Now at 6 weeks and about 8 1/2 lbs:

I generally avoid photographing old, well loved diapers because it’s kinda gross. However, I thought it was interesting to see how this diaper has held up. Keep in mind that I had a very tiny stash for more than a year, so this was washed a lot!

The inner and the exposed part of the elastic are pretty dingy, but most of the wear is in the velcro. Some choose snaps to avoid this, but I think it’s really held up pretty well for as old as the diaper is, and as much use as it’s received. My husband really prefers velcro, so that’s what I choose most of the time!

So there you have it! The Thirsties Duo Pocket diaper!
