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 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
• Larger fit for toddlers (fits 35-70 lbs.)
• Modular Snap In Soaker System allows for customization
• Easy closure replacement
• Fairly and conscientiously made in China
