Roll out the red carpet for Thirsties Duo AIO.  Finally, an All In One reusable diaper that truly challenges the convenience and trim-fit of a disposable diaper.  Many All In Ones of the past were pricy, tough to clean, and impossible to customize in size and absorbency.  The revolutionary Thirsties Duo AIO offers absorbency, waterproof protection, and adjustability all rolled up into one stylish, comfortable and extremely effective cloth diaper.



The unique design of Thirsties Duo AIO offers a trim-fitting, easy to use, customizable diaper that also cleans up like a dream.  This incredible diaper provides a lot of pack for your punch and includes Thirsties’ signature tunnel system which enables stuffing of additional absorbency when needed.  To lighten the load on your pocket book, this diaper has been thoughtfully devised so that just two sizes will reliably fit from birth all the way to potty.



A snap down rise and the adjustable snap or Aplix closures ensure that this diaper will accommodate babies of all shapes and sizes.  A built-in three-layer microfiber terry soaker absorbs an amazing seven times its weight in liquid.  While sporting a Thirsties Duo AIO, your baby experiences nothing but soft, buttery, stay-dry fleece against her sensitive skin. All in all, Thirsties Duo AIO gets a BIG thumbs-up from your wallet, your family, your daycare facility, and your occasional caretakers alike.


Please consider pairing the All In One with our Hemp Inserts or Fab Doublers for heavy wetters or extended, overnight use.

Proudly manufactured in the USA

Care & Use

Wash your Duo AIOs once before use, with a cloth diaper safe detergent.

At every wash cycle:
- Prewash on cold
- Wash on hot
- Double rinse
- Hang to dry or dry in the dryer on low or medium

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.

  1. Size 2 is better, Great AIO for dads and sitters

    Posted by Unknown on 25th Jul 2012

    After having a fail with size 1 leaking with my baby, when he got big enough for size 2 I was pleasantly surprised it did not leak! I am very happy that they fit and are doing great. Love these diapers!

  2. EASY

    Posted by Unknown on 17th Jul 2012

    what an easy diaper makes my life soo easy. does take some time to dry but dries faster on a line. will not buy another pocket diaper again!!!

  3. Love these!

    Posted by Lisa K on 6th Jun 2012

    I am a big fan of these diapers! They are really trim for an AIO and they dry really fast. I love that you can add more to them for at night. We always get a great fit and never get leaks. Love them;-)

  4. Good diaper

    Posted by Jessica K. on 6th Jun 2012

    I love how easy this diaper is to use. It fits my daughter great and has good absorbancy. The prints are also super cute. My only dislike is that it takes so much longer then my other diapers to dry.

  5. Best Out-and-About Diaper

    Posted by Nicole S on 5th Jun 2012

    These diapers are great when we're out of the house. I can take one off, stick it in the wet bag, and dump the whole thing in the pail when we get home. It's nice not to have to deal with the unstuffing. Honestly, I wish my whole stash was made up of these.. they'd be great at home as well.

  6. Cute prints, flexible

    Posted by Danielle Shannon on 3rd Jun 2012

    These are super comfy on my son. Easy for on the go. Not a super soaker for us, as he will leak if he is having a heavy wetter day. But we have owned these in both sizes and will continue to use as an everyday diaper.

  7. Great Diaper & Price

    Posted by Irene on 1st Jun 2012

    This is a great diaper and the price is even better! It is very easy to use (no stuffing) and it is also very absorbant. This is also a great diaper for those that aren't comfortable using cloth since it functions just like a disposable diaper.

  8. Amazing AIO

    Posted by April Hunt on 31st May 2012

    This is such an awesome and trim diaper. It isn't as bulky as alot of brands so pants fit a bit better if you have a pair that are a bit more snug. Super soft inside and really cute colors and prints!!

  9. favorite AIO

    Posted by Lexi Conklin on 30th May 2012

    this is by far my favorite AIO if not my favorite diaper. great price, and never have any leaks and its super absorbant! i love it!

  10. Great diaper!

    Posted by Annie on 30th May 2012

    I really love this diaper. It fits my chubby bubby like a glove and we never have leaks. I like that you have the option to add additional absorbency if needed with the "tunnel" effect (that's what I like to call it.).

  11. Super Diaper

    Posted by Elise on 1st May 2012

    I have not found a diaper to surpass the quality I found in the Rumparooz GD OS pockets... until now. These Thirsties Duo AIOs fit my chunky 10-month-old really well, are trimmer than the RARs, and don't suck the wings down into the diaper like the RARs do after a lot of baby traveling. They are extremely absorbent and easy to wash. The poo seemed to rinse (with the diaper sprayer) better off of the Thirsties stay-dry fleece than off the RAR stay-dry fleece. Talon can go half a day in a Thirsties AIO, when he can only go up to 3 hours in the RAR. I haven't tried stuffing the Thirsties with an extra insert for nighttime, but I think it will be leak-proof. I am selling my RARs to make room for the more cost-efficient and more absorbent Thirsties.
