Thirsties One Size All In One Diaper - Trim, Stylish, Comfortable!

From Thirsties comes their new One Size All in One reusable diaper, which truly challenges the slim-fit and convenience of a disposable diaper. This diaper offers absorbency, waterproof protection, and adjustability all rolled up into a stylish, comfortable and extremely effective cloth diaper.

The team at Thirsties thoughtfully designed this all in one diaper. The built-in, three-layer microfiber terry soaker absorbs an amazing seven times its weight in liquid. The soaker is topped with a stay-dry microfleece which keeps your baby feeling dry. An additional layer of terry lies between the microfleece and PUL body of the diaper providing a last line of defense. The soaker is sewn in on one side (at the top of the diaper), which makes adding extra absorbent layers a cinch and tremendously decreases drying time…it’s the fastest drying diaper Thirsties has ever created!

Thirsties One Size All In One Diaper Features

  • More absorbent and dries 3 times faster than the previous Duo All In One.
  • Convenient, trim fitting, and absorbent.
  • Goes on in one simple step - cloth diapering doesn't get easier.
  • One size diaper provides a customizable fit for most babies from birth to potty.
  • 4 total layers of absorbent microfiber terry, a microfleece liner and a reliable waterproof exterior.
  • Available with hook & loop or NEW snap configuration with two rows of snaps.
  • Gentle elastic around legs and waist provide protection against leaks.
  • Stay-dry microfleece liner provides wetness protection.

Available In Your Choice of Hook & Loop or Snap Closure!

Both hook & loop and snap closures are available on Thirsties One Size All in One. While many families prefer hook & loop closures because of the simple, secure fit they provide, snap closures do have a few advantages of their own. They are practically indestructible and are more unyielding than our hook & loop closures, making them more challenging to unfasten for a toddler who prefers to go naked.

Fiber Content:

  • Outer - 100% polyester with waterproof urethane coating
  • Inner liner - 100% polyester microfleece
  • Inner absorbency - 1 layer of microfiber terry
  • Inner soaker - 100% polyester (3 layers of microfiber terry topped with layer of microfleece)

Care and Use

Before use: Wash 1-3 times using a cloth diaper safe detergent.

At every wash cycle: Prewash on warm. Wash on hot. Add another rinse on warm. Hang dry or dry in the dryer on low. Turning the diapers inside out may speed dry times. If the diapers are stiff after line drying, you can throw them in the dryer on low heat with some wool dryer balls to soften them.

Important notes:
Use enough water to soak and cover the diapering items and allow them to agitate.
Avoidthe following:

  • Laundry boosters/additives
  • Sanitize or Whites cycles on HE machines
  • High heat in the dryer
  • Pure Soap
  • Bleach
These practices and/or additives can void the warranty on your Thirsties products.

Not bad

I liked these diapers at first but now at 9 months they just don't hold as much. I prefer the NAIOs.

A go to diaper!

My stash is mostly Thirsties AIO. I simply add a hemp insert when needed and done! So easy to wash and dry. The best in terms of a happy medium between pockets and AIO. Necessary for a busy mom of four!

too small, not absorbent enough
Reviewed by:  from utah. on 7/26/2018
These are soft and cute. They are nice for the first months because they have a smaller fit. However our baby outgrew them pretty quickly, and they really aren't very absorbent. I had to use a doubler to make them last more than two hours tops. The NAIO is the way to go.

Not a fan

The prints are amazing, but they dont fit my chunky 3 month old very well. I like a little more stretch in my diapers.
