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 is unique among cloth diaper all in ones (fits 35-70 pounds) because it comes with everything parents need to cloth diaper a larger toddler or older child. 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
  • Larger fit for toddlers or older kids (fits 35-70 lbs.)
  • Modular Snap In Soaker System allows for customization
  • Easy closure replacement
  • Fairly and conscientiously made in China

      O.N.E. Cloth Diaper - FAQ

      Before laundering, dispose of the solids. Remove the Outlast Closure Hook/Loop strips before placing Big O.N.E. in your diaper pail. We recommend removing Soaker Pads before placing them in the diaper pail so that each piece of the diaper is optimally agitated. Choose warm or hot water and enough of your favorite good-cleaning detergent.

      To cloth diaper full-time with the Big O.N.E. Diaper, you will spend between $600-$650. Remember that you’re saving 5x that by not buying disposables. To use the Big O.N.E. Diaper as your child's overnight cloth diaper, you will spend just over $100.

      For full-time cloth diapering, we recommend at least 24 diaper changes per child to best spread wear out among all the diapers in your supply.

      For using the Big O.N.E. as your child's overnight cloth diaper, we recommend having at least 4-6 as nighttime cloth diapers.

      My bed wetter can go from a dry overnight to Hurricane Katrina on the second, I was understandably hesitant in my expectations of this diaper. I’m happy to report that the Big O.N.E. has exceeded ALL expectations in performance and dryness. For reference, I’m using on a 5 year old who is about 4 feet tall and weighs approximately 44 pounds (70th percentile in growth group). Fit is perfect and we’re using the Velcro for now, the tabs touching but not overlapping. No leaks, not a one, only some mild saturation on the waistband of the PJ bottoms if they happen to flip inside the diaper. Very pleased with this product, would LOVE to see them design a pull-up for this age/size group. Also, washing is so simplistic, I have even washed them with our regular clothes. They do take almost twice as long as synthetic cloth diapers to dry though, due to the natural fibers in the liners.


      This is my daughter’s favorite pattern. She’s 4 1/2 and late hitting her milestones. This bigger size has been a lifesaver. The quality and materials are top notch. I won’t ever recommend or use any other cloth diaper but Grovia.


      Best reusable diaper on the market. I couldn’t live without these bigger size Grovia diapers. High quality made w/high quality materials. I highly recommend.
