Want an innovative and easy to use diaper?  Thirsties Duo Diaper is the answer!


  • A two-piece diapering system combining an absorbent insert and waterproof sleeve diaper
  • Seven thirsty absorbent layers
  • Microfleece liner provides wetness protection and stain resistance
  • Grows with your baby so you only need two sizes from birth to potty!
  • Easy stuffing and one-step cleaning
  • Pliable, breathable ultra-comfortable waterproof exterior

Here's the Scoop on the Duo Diaper:
  • Thirsties Duo Diapers are completely waterproof yet remain breathable, pliable, and very comfortable for your baby's delicate skin.
  • The ultra-soft microfleece liner on the inside protects baby's skin from wetness and also resists staining.
  • The handy sleeve design features openings on both sides of the diaper between the microfleece and waterproof layer.
  • The duo openings featured in Thirsties Duo Diaper enable easy insert stuffing from either side of the diaper and also make for easy cleaning.
  • There is no need to remove the soiled inserts when washing-your hands will remain clean!
  • Simply toss your soiled Thirsties Duo Diaper in the laundry and the inserts will agitate free from the diaper in the washing machine.

Here's the scoop on the Duo Diaper inserts:

  • Thirsties' specialty inserts feature two layers of serged microfiber terry snapped together with five serged layers of hemp jersey; seven thirsty layers in all!
  • Microfiber terry is a fast absorber designed to rest closest to your baby's skin (beneath the microfleece sleeve); hemp is a stable absorber and pairs perfectly behind the microfiber terry to add more absorbency and to prevent compression leaking. 
  • Thirsties' new hemp jersey is like no other on the market! Thirsties has a knitter right here in the USA to custom knit the hemp textile to their specifications. You will find this hemp is thicker, softer, and holds-up better than any other on the market!

Duo Diaper Sizing

Duo Sizing Options:

In an effort to maximize affordability of cloth diapering Thirsties created our Duo line. This means all Duo products are available in 2 sizes which will cover your baby from birth to potty. Each of the two sizes in the Thirsties Duo line feature three rows of snaps to adjust the rise to your baby’s shape; it is like having THREE sizes in one.

Care & Use

Before Use: Wash your Duo Diaper shells along with the terry portion of the insert once before use. The hemp portion of the insert needs to be washed and dried at least three times before use to rid the fibers of the natural oils. This is done separately from your other diapering products for the first 3 washes. Inserts will be fully primed and at their maximum absorbency after 8 wash cycles.

At every wash cycle:

  • -Prewash on cold
  • -Wash on hot
  • -Double rinse
  • -Hang dry the shells, or dry in the dryer on low. Hang dry the inserts, or dry in the dryer. 

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. You may use high heat on inserts.
