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.

  • Goes on in one simple step (no extra parts!) - the diaper of choice for the occasional caretaker

Care and 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.

Best fitting diaper for my little guy
I have a couple of different types of AIO and this diaper is definitely the most trim out of all of them. It fits my little guys skinny legs the best and I've had no problem with leaks or blow outs! I love my polka dance!

Great, but a bit small
We got a size 1 for our then 12lb 2 month old. When it arrived we were already on the biggest setting. He's now 14lbs and has pretty much outgrown it. We are going to end up selling it after less than a month of use. That said- the design is great. It dries a lot faster than I expected and is not at all bulky. I just wish we'd gotten it in a size 2!

Great for daytime
I really like this diaper. We use it often during the daytime and it's usually the one I grab to throw in the diaper bag when we go out. So easy to use. I tuck a thirsties fab doubler in the pocket and I've never had a leak. I did try it at night once and it wasn't the best choice. I bought it because of the print (the pink argyle one) and it's one of the cutest diapers we have.
