Bayrli Outer


Taxes incluses. Frais de port calculés au paiement.

Color: Berry Blue

The Bayrli Outer is our simplistic and effective diaper cover.

This is a truly leak-proof and blowout-proof option when paired with any Inner from us.

Carefully designed to snugly fit over the Bayrli Inner, and with extra elastics and double gussets to prevent leaks, it is an essential companion to the Inner. We have also designed this fit to last your baby as they grow with a double row of snaps on the waist allowing you to adjust the size of the waist independently to the legs. This way, you only need one size for your baby until they are potty trained.

Choose from a cool palette of prints and colors. Our Bayrli Outers are made of recycled fabric from 100% post-consumer plastic bottles!

Waterproof yet breathable, stretchy yet snug, and capable of being reused multiple times between washes. Clever design at its minimal best for you.

Waterproof shell: 100% polyester

Certification(s): CPSIA compliant. Tested by a Consumer Product Safety Commission (CPSC) accepted test lab. Free from harmful chemicals, materials, and metals.

Lovely print and such a fantastic fit. The containment is amazing on these nappy covers. I usually used Little Lamb wraps on our baby but swapped all of those out for the Bayrli Outers as I could not get over how well they suited our little girl. We also needed something without velcro as she had learned how to open those. The Outers are soft, easy to wipe clean, and easy to wash. No negatives in my book after a few months of wear and still look and feel as if they just arrived.

Fit our newborn and toddler!

Use these and flats most days with no issues and over the hemp for night. They have soft elastics in the gussets at the legs and belly and fit both of our kids. Our newborn has skinny little legs and these have been amazing! I’m shocked they fit a 10lb baby so well and also fit my 37lb toddler who is a bit on the chunky side.
If you have snap in inserts like Buttons or Petite Crown you can use this cover with them and it fits as well which is handy!


Blueberry and whale print is gorgeous. Super fit on my 15wk old girl and perfect for fitting over our prefolds.

Lovely design

We love these nappy covers. They fit well over out fitted nappies, flats, prefolds, and preflats securely and we haven't had any leaking issues after about 3 months now.

The fit is the same as the pockets we use during the day which is nice.

Perfect fit for every brand I have. Nothing bad to say really.


I have a few of these covers and find they fit great over all of our nappies. I love that I can swap my Buttons inserts and even the hourglass Petite Crown hemp fleece insert into the cover (a plus that they use the centre snap and stay in place!!). After using both day and night, I don’t even reach for our other covers as these have been absolutely blast proof for our baby. Also great to see the same fit from the pocket and aio so we know how they will work for us and which snaps to use at the rise and waist. Another plus is with our 30+ lbs baby that she has a ton of room to grow with these and they truly will last until she’s potty trained unlike some of our other nappies she’s already out grown and we’ve had to sell on. 5*

Good product

Love the flaps to hold prefolds in place


Lovely print quality and very happy with the fit. I use Thirsties usually so just got this to try and have been impressed tbh.

Great fit

I love the fit of these diaper covers on our baby - normally we used Petite Crown covers, but these are 100x better in fit over all of our flats, prefolds, and fitted diapers. Super versatile and not bulky at all. 5*
