  • Our best-selling diaper, O.N.E, just got BIGGER and BETTER!  Introducing Big O.N.E., a diaper designed to meet the absorbency and size needs of larger kiddos.

    The Big O.N.E diaper unique among cloth diaper all in ones (fits 35-70 pounds) because it comes with everything parents need to cloth diaper a baby: enough absorbency to forget boosters and doublers (even overnight), two built-in closure options, and a heavy-duty construction that is built to last.

    The Big O.N.E. features a unique Outlast closure system that gives you the ability to choose between Hook & Loop and Snap closures, and the ability to buy a replacement kit when your Hook & Loop wears out. Big O.N.E's absorbency comes from a hidden body layer PLUS our one-of-a-kind cotton, channeled soaker design that is trim yet absorbent. All with the same amazing quality you've come to know and love in GroVia products. 

    No need to choose between Hook & Loop or Snap closures

    With the Big O.N.E., you can have both! The removable Hook & Loop closure is perfect for those who love a “no-hassle” fit but want to transition to a snap closure later on. 

    • Built-in extra absorbency means the perfect nighttime solution
    • Lasts from birth to potty learning (fits 35-70 lbs).
    • No prepping - can starting using right away
    • Modular Snap In Soaker System allows for customization
    • Easy closure replacement

Glad to have a big kid option

Very glad to have a cloth diaper option for my 5 year old who still needs a diaper at night. We are still troubleshooting a little bit as it seems a little of the inner absorbent layers tends to stay exposed and so it wicks the wettness and it ends up getting his pjs wet.... maybe I just need to play around with how I snap it and how I snap the rise snaps down- I've tried a couple different ways and but still it kind of folds outwards (if that makes sense). But I'm so happy to be using fewer disposable diapers!

Super absorbent!

Got this for my 7 year old who has a hard time waking at night. It’s fantastic for the nights she doesn’t wake up. Super absorbent!!! So glad I’m not wasting $ on pull-ups anymore! So glad to have a bigger size!!!

Perfect for Bedtime

I got these after our nighttime trainers started to become too tight. They are perfect on the smallest setting for my 3yr old, 35lb daughter. There is plenty of absorbency, she has yet to completely soak the entire diaper.
