OsoCozy Flat Diapers (Unbleached) - dozen

Our softest 100% cotton flat diapers are unbleached, birdseye weave. Tried and true for over a decade, these are a favorite among our customers.

  • One layer thick
  • Measures 27 inches by 30.5 inches - sized to shrink square for easy folding
  • Weigh just over 3 ounces each - which is heavier and more absorbent, than discount brands in chain stores
  • Unbleached for extra softness

The original cloth diapers

Flats are the original cloth diaper still used around the world. Birdseye flats are durable one-size diapers, making them the most economical cloth diapering choice. These diapers do require folding with use of a diaper fastener and diaper cover.

So many uses

Flat diapers can be used alone for cloth diapering, as absorbent inserts for pocket diapers and AIO cloth diapers.

Such a soft, cotton cloth has a lot more uses: dish towels, burp cloths, lap pads, changing pads, bibs, wash cloths, baby wipes, or gentle, lint-free wipes for your car.

Easy care

Because flat diapers are only a single layer thick, they dry quickly on your clothes line or in your dryer. For those who have little access to washing machines, flat diapers are a great choice. Hand washing is much easier than you expect it to be.

If you have patience and are willing to do some minimal folding, then using these diapers are by far the least expensive way to comfortably diaper your baby.

Why unbleached cotton diapers?

Unbleached cotton birdseye hasn't been treated with harsh chemicals, so the diapers retain their softness once washed. Keep in mind unbleached flats must be washed 2-4 times before use. Since the diapers still contain cotton oils, they must be washed thoroughly in order to become soft and absorbent.

Also available in Bleached (dozens) and Organic (dozens).

Ask a Question
  • How thick are these diapers? The issues I've had with flats so far, is they're made of super thin material that I can literally see through - I wouldn't even consider the ones I have for a diaper.

    Our flat diapers are 1 layer thick of 100% cotton in a birdseye weave.  They are meant to be folded so that you get multiple layers in the pee zone.

Flats are amazing for the fact even if they shrink a little they are big enough to still fit your baby with room. Though these are not absorbent enough by themselves so you have to change frequently and maybe add a liner. I also use a cover since I don't want to change her clothes every time I change her diaper. Overall I'm still happy with the flats.

Just buy them.

Originally purchased these as a cheaper alternative to Green Mountain Diapers flats to see if I would like birdseye flats and WOW. I honestly can't imagine a flat getting much better than this! Washed 6 times to prep and they shrunk perfectly square at 26" x 26". They are SO soft and absorbent and thick. If you're looking to save some money JUST BUY THESE!! Amazing.


I decided to purchase two dozen of these to use when my little one was battling a yeast rash. I knew I would have to disinfect our diapers during every wash if we were going to kick this rash and I didn't want to "ruin" my "good stash" (AIO/AI2's). These were cheap enough that I didn't care if I ruined them. To my surprise, not only did they hold up remarkably well to 8 weeks of continuous use and frequent disinfecting, I have fallen in love with them. They're so easy to wash and using the pad fold is just as quick as an AIO. Needless to say, I've purchased more!

I would recommend these to others.

I love these diapers! They are large enough to last a good while and soft enough to keep baby comfortable.
I also love the instructions on how to fold these for a good fit. Thank you. I would recommend these to others.

Great from newborn-potty train!

I purchased 2 dozen of these and only need to use a cover for them. They are wonderful! I like the fact that I can custom fold them to meet the growing needs of my baby. After several washes before putting my baby in them they are soo soft and absorbent!
