Details
Thirsties Duo Diapers are easy to use and even easier on your wallet! The adjustable rise of this diaper design means one size will last twice as long. In fact, you'll only need two sizes to cover your baby from birth all the way to potty-learning. Period!
Similar in feel and fit as our best selling Duo Wrap, Thirsties Duo Diapers are completely waterproof yet remain breathable, pliable, and very comfortable for your baby's delicate skin. The ultra-soft microfleece liner on the inside protects baby's skin from wetness and also resists staining. Our handy sleeve design features openings on both sides of the diaper between the microfleece and waterproof layer. The duo openings featured in Thirsties Duo Diaper enable easy insert stuffing from either side of the diaper and also make for easy cleaning. There is no need to remove the soiled inserts when washing-your hands will remain clean! Simply toss your soiled Thirsties Duo Diaper in the laundry and the inserts will agitate free from the diaper in the washing machine.

Our Duo Inserts provide double the duty as well! Thirsties' specialty inserts feature two layers of serged microfiber terry snapped together with five serged layers of hemp jersey; seven thirsty layers in all! Microfiber terry is a fast absorber designed to rest closest to your baby's skin (beneath the microfleece sleeve); hemp is a stable absorber and pairs perfectly behind the microfiber terry to add more absorbency and to prevent compression leaking.
By the way...did you know that Thirsties' new hemp jersey is like no other on the market!?! We (finally) found a knitter right here in the USA to custom knit the hemp textile to our specifications. You will find this hemp is thicker, softer, and holds-up better than any other on the market.
Plus, Thirsties Duo Diapers are a cinch to use...even for the occasional caretaker. Simply stuff the insert in the sleeve of the diaper and wrap around your baby. The durable hook-and-loop closures of Thirsties Duo Diaper provide a perfect and secure fit at every diaper change. Thirsties' signature leg gussets provide advanced leak-proof protection and our bindings are super soft against your baby's skin. Both Duo sizes offer convenient fold-over laundry tabs to protect your hook-and-loop closures from trapping lint in the wash.

Each of the two sizes of Thirsties Duo Diaper feature three rows of snaps to adjust the rise to your baby's shape; it really is like having THREE sizes in one. Pairing such adjustability in rise with our signature leg gussets make this diaper the most versatile on the market. Whether your baby is tall or short, thin or chunky, this cover will keep those messes contained!
Let's face it...'one-size' options tend to be too big on the average newborn and too small for most toddlers over two years of age. What this means is that the 'one-size' option truly only fits your baby properly when he/she weighs between 10 lbs to 32 lbs. Alas, our findings confirm that the diaper label 'one-size' simply does not live up to its claim. Most families purchasing a 'one size' diaper would actually end up purchasing a newborn size, a 'one-size', and a toddler size: THREE sizes from birth to potty! Not ONE.
Therefore, in the end, Thirsties Duo Diapers are truly the more reliable and more affordable option when comparing to a 'one-size' system.
Duo Sizing Options:
In an effort to maximize affordability of cloth diapering Thirsties created our Duo line. This means all Duo products are available in 2 sizes which will cover your baby from birth to potty. Each of the two sizes in the Thirsties Duo line feature three rows of snaps to adjust the rise to your baby’s shape; it is like having THREE sizes in one.
Care & Use
Before Use: Wash your Duo Diaper shells along with the terry portion of the insert once before use. The hemp portion of the insert needs to be washed and dried at least three times before use to rid the fibers of the natural oils. This is done separately from your other diapering products for the first 3 washes. Inserts will be fully primed and at their maximum absorbency after 8 wash cycles.
At every wash cycle:
-Prewash on cold
-Wash on hot
-Double rinse
-Hang dry the shells, or dry in the dryer on low. Hang dry the inserts, or dry in the dryer.
Important notes:
Use the highest water level possible when washing a full load of diapers.
Please avoid using the following for diapers or covers with components such as elastic, Aplix, and lamination:
Sanitize cycles on HE machines
High heat in the dryer
Pure Soap
Vinegar
Washing Soda
Chlorine Bleach
These practices and/or additives can void the warranty on your Thirsties products. A 15 minute cycle on hot in the dryer once a month is beneficial to lamination, and will not void your warranty. You may use high heat on inserts.

Testimonials
Just wanted to say-I LOVE LOVE LOVE the duo diaper! I think I have tried
about every cloth all in one and pocket diaper out there, and the duo diaper
was my favorite, and most reliable of the stash. Rarely have I ever have an issue
with leaking, which is not my experience with the other diapers we have tried.
We almost gave up on using cloth because of leaks until we tried your
product. My only suggestion would be to add some new prints. I have the cool
stripes and the blackbird one, but would love some new prints to get for my
little guy. I get so many compliments on my Thirsties! Thank you for all
that you do!
The size one diaper and covers fit my daughter perfectly, and are so easy to use (even with a very wiggly baby). Not only are they cost effective, convenient, and super absorbent, but they are super cute. I have actually gotten compliments on her diaper/diaper covers from strangers.
I was a little hesitant to put my daughter in a cloth diaper at night, thinking that a disposable diaper would wick the wetness away more efficiently to avoid diaper rash. Boy was I wrong! We have used the duo diaper at night now for the past 8 weeks without a single rash or red mark. In addition, this is the only cloth diaper that hasn’t leaked or allowed for a diaper blowout. I can’t tell you how happy that has made me!
First off love your duo diapers. Love the leg gussets! It's the first diaper to actually contain my daughter's breast fed blow outs. And, no leg leaks which means less washing clothes. They also fit great under her clothes without too much bulk.
Thirsties Duo Diapers are my absolute favorite night time diaper! We go 10+ hours at night with no leaks, and the fit is wonderful around the legs and stomach! I am so happy with these diapers! I have two, and I plan to buy more!
