Ditch the bulk! Thirsties® Duo Fab Fitteds are shaped for a trimmer appearance and fabulous comfort for your mobile baby. And now, thanks to their latest innovation, they're even easier on your wallet. Just like their economical Duo Diaper and our Duo Wraps, the Thirsties® Duo Fab Fitteds feature an adjustable rise, which 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.

Expertly crafted from stretchy, buttery soft textiles with a stay-dry liner, these super cute fitted diapers offer superior wetness protection for your baby's delicate skin. Encased elastic wraps snugly, yet gently, around your baby's legs and torso to provide the very best protection from leaks. And, Thirsties® Duo Fab Fitteds are easy to use. Simply wrap around your baby and secure with the easy-to-use Aplix or sturdy snap closures for a secure, custom fit.

Want a completely watertight diapering system? Remember, although you’re not going to want to cover up these adorable, ultrasoft diapers, Thirsties® Duo Fab Fitteds are not waterproof on their own. At times when you do need total protection, we recommend pairing your Thirsties® Duo Fab Fitted diaper with a Thirsties® Diaper Cover or Duo Wrap for the perfect adjustable fit and unstoppable performance.

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. Each of the two sizes of our Duo Fab Fitted diaper feature three rows of snaps to adjust the rise to your baby's shape; it really is like having THREE sizes in one.

Only the best components come together to make Thirsties® Duo Fab Fitted diapers. The internal soaker is composed of spongy microfiber terry that can absorb up to seven times its weight in liquid! A maximum absorbency of 18 oz. makes this diaper appropriate for both light and heavy wetters alike. There is a tunnel behind the soaker which allows for stuffing additional absorbency, and for better washing and quicker drying. Touching your baby's skin is an entirely unique microfleece that is oh-so-soft to the touch and works to keep your baby feeling dry, thereby helping to prevent diaper rash. Textile pilling and stained diapers is a thing of the past with the help of the specially-made microfleece inner layer. You will likely notice that this diaper maintains its appearance and supple feel longer than many other brands on the market. Finally, the velvety cotton velour outer layer comes in a variety of fresh, fun color options (plus white).

And just when you thought it couldn't get any does. Thirsties® Duo Fab Fitted diapers are made in the USA by a group of extremely talented women, many of whom sew in the comfort and convenience of their own homes.

great for day, not for night , 1/9/15

these are a great, trim fitted diaper, but fit on the small end and a I found were not absorbent enough for night time use, even with extra boosters.
I wanted to love these... , 7/25/12

I loved thirsties in size one when my kids were small, but once they grew out of those, I found the size two thirsties doesn't quite have the same kind of fit. These fit great through the legs, and it was easy to stuff extra hemp inserts or a hemp prefold for night use, but I found there was a lot of extra bulk at the front of the diaper. As well, I'm not fond of microfiber, and found these starting to hold onto stink, especially since I was using them as an overnight diaper (12 hours of toddler pee makes a lot of stink!).
work great for newborns! , 10/26/11

i only used these on my newborn, but they fit right away (at 8lbs) i have a skinny long baby and they fit great on the legs and waist, no leaks! i love that they have the 2 one size options, the size one fits much trimmer than a regular one size fitted. the velcro does get a little frayed with wear and washing.
