I've been reaching for my Duo Diaper first during diaper changes!

  • Mar 8, 2010
All of the best cloth diapers started out as a mom's vision and solution to ill or non-fitting cloth diapers and covers. The president and founder, Erin, started Thirstie's when she couldn't find a diaper cover that suited her baby's needs. The first covers were patterned, cut, and sewn at her dining room table with her secondhand sewing machine. After 18 months of testing and tweaking the covers were finally released to the public and this great company was born.
All of Thirstie's diapers and covers are made in the USA by a small group of moms who get to work in the convenience of their own homes. All of the components are USA-sourced which helps support domestic textile mills and reduce their carbon footprint. 
I was given the chance to review the Thirstie's Duo Diaper. I chose ocean blue in size 2 which fits 18 to 40lbs, approximately 9-36 months. My son is 8 months old and approximately 21lbs.

Fit: I can tell this diaper is going to last us until Eli is out of diapers. He fits into this diaper on both the smallest and 2nd rise setting. In this photo he is shown wearing the Duo Diaper on the 2nd rise setting (and no, he can't stand up unassisted yet, this picture is an illusion)! This diaper has a fairly trim fit, it's a little bulky when stuffed with both inserts, but Elijah doesn't mind, and I certainly don't mind. What's fluff when you don't have a fluffy bum!? The hook & loop closure is a cinch to use, and it has crossover tabs so these diapers will fit even the skinniest of babes (I own some Thirstie's Fab Fitteds as well and their hook & loop closures have held up the best out of all diapers I have owned for 8+ months). One thing I really love about Thirstie's are the leg gussets! I have never had a leak in this diaper or with my Thirstie's covers.

Performance: I have had the luxury of testing this diaper out with both poop and pee and it's been great for both! No leaks or blowouts, and the absorbency is wonderful. I've put this diaper on Elijah overnight several times and I won't hesitate to use it overnight again. This diaper comes with two inserts that snap together, a 100% microfiber terry insert and a hemp jersey insert which is 55% hemp/45% cotton. I always use this diaper with both inserts just because they are super absorbent together. The inner diaper layer is microfleece which wicks moisture away from your baby so they stay dry!

Ease of use: The Thirstie's Duo Diaper is designed with two pocket openings, one in the front and one in the back. You don't have to take the insert out before throwing the diaper in the wash, it agitates itself out (yes, even in a front loading machine!) which means one less step for you. Cloth diaper laundry is my favorite chore, but I am always happy when I have one less diaper that I need to worry about taking the insert out of. The pocket openings are wide, so stuffing the diaper before use is easy. This diaper is definitely babysitter and husband friendly, which means it's very easy to use :)

Value: The suggested retail for the Thirstie's Duo Diaper is $18.50. You can completely diaper your baby from birth to potty learning with 12 of each size (24 diapers total) for $444. Considering that you would be spending thousands more with disposable diapers makes $444 look really good. These diapers are such great quality with superb performance that they are worth every penny!

We love this diaper. It works great, looks cute, and is easy to use. I'll definitely be buying some more of these!

Thirsties Duo Diaper size 2, 19 pounds
I absolutely love love love the Duo Diaper, I had to rave about it here! It combines the ease and convenience of a pocket diaper with the leak proof protection of the Thirsties Fab Fitted and Duo Wrap. Thirsties sent us one Duo Diaper in size two to try on our 11 month old, 19 pound baby girl.       FIT: I have tried one-size diapers and while they are OK, they will always be a little big on a newborn and a little small on a two year old. The Duo Diaper solves that …

Without an insert it works great as a swim diaper too! Easy on/off and easy to wash. Plus a PERFECT little beach bum fit!
