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.

    Best reusable diaper for Toddler, Tween, Teen, Petite Adult & ALL Heavy Wetter's!

    Just how BIG is a BIG O.N.E?
    Well let me tell you a bit about myself first. I'm a very thin framed adult that suffers from incontinence, I'm always on the search for top notch products.
    I am 6' and 135lbs with a 29" waist, and yes, .....I wear Big O.N.E.'s!!! They are THAT BIG!!!
    That's not to say they won't fit your little one, they are very stretchy, and have many fastening positions available to get a great fit for a large range of body shapes and sizes, no matter the age.
    For me, Big O.N.E's are a very discreet low rise option that sits just below my pants line. When they say 'For Heavy Wetter's" they mean it! These are some extremely thirsty diapers. I can actually sleep for up to 6 hours and still wake up to a dry bed, and still feel dry too...simply AMAZING!
    I do wish they would come out with a "Bigger O.N.E" version, geared more towards the 70 -125lb range, for nights that I may sleep more than 6 hours. Perhaps 4" more rise, 3" more rear wings, 6" longer hour glass shaped channeled snap in pads?

    They’re really big!

    I purchased these for my 3.5 year old daughter, who weighs about 30lbs to wear during naps and to bed. They’re huge! So I rarely put them on her, as I feel they’re too bulky. Instead, I’ve been putting her in the grovia trainers with the extended elastics for naps (forgive me for not knowing the actual name of the products). At night, we reluctantly use disposable diapers, and will likely do so until she gets a bit bigger, and these fit better.

    But as a review for the product, they’re extremely absorbent, and would recommend, so long as they fit your little (big) one.

    A++ worth every penny

    I LOVE THE BIG ONE DIAPER! My 2 year old is in the 99% for height/weight (35 lbs, 3 ft 4 inch) and was on the brink of outgrowing a size 7 disposable diaper. The BIG ONE is the perfect solution for saving the environment/money in the long run, not relying on the delayed supply chain, and has provided me with a custom fit for my larger toddler. My only criticism is I wish it was 100% cotton, but my toddler has not had a diaper rash since using the diapers.
