  • Single layer of GOTS certified organic cotton
  • Stretchy, soft knit cotton provides a comfortable and customizable fit
  • Very versatile--can be folded in numerous ways to maximize absorbency where your baby needs it

Thirsties Organic Cotton Flat is a single-ply, one-size-fits-all diaper that can be folded in numerous ways to provide customizable absorbency. We recommend washing and drying your Thirsties Organic Cotton Flat at least three times before use to rid the fibers of natural oils for maximum absorbency.


Try different folds to find the right absorbency concentration for your baby.  A fan favorite and the fold we recommend due to its simplicity and performance is the pad fold.  Simply pad fold your Thirsties Organic Cotton Flat, and lay it in a Thirsties Duo Wrap or Diaper Cover for a complete diaper system for your baby. Additionally, Thirsties Organic Cotton Flats may be used for additional absorbency in Thirsties Pocket Diapers. Very soft and stretchy jersey knit. 


If using a fastener with our flats, please note fasteners can leave small holes that shouldn’t affect function, but the holes are not covered under our warranty.  If you choose to use a fastener, rotate your flats during usage so different sides are fastened each time. Sold individually. Price is for one diaper. 



Pre Wash – Roughly 29” x 27.75”

    So soft

    I really like this flat. It absorbs a lot without feeling too bulky on my 5 week old. It is really soft and cuddly. I could see it also be used as a swaddle.

    Ordered 10 of these to use as swaddling cloths, burp pads, etc. for my son and daughter-in-law who just had their first baby. Loved the softness, size and all around utility of them so much that I am ordering 10 for my daughter who is due in a few months. These diapers remind me of a softer, more useful version of the cloth diapers my mother used for all of us -- she always had one on her shoulder when there was a baby in the house.
