bumGenius Original 5.0 One-Size Pocket Diaper

The original bumGenius pocket design that introduced parents to what is now one of the best-selling cloth diapers in the world - and it just got even better!  An updated stay-dry inner fabric that stretches to provide a secure fit and a redesigned pocket that is more trim across the back, the Original 5.0 also includes the same patented features that make bumGenius so genius!  New elastic too!

  • NEW Elastic!
  • NEW! Updated stay-dry inner fabric that stretches to provide a secure fit
  • NEW! Redesigned pocket that is more trim across the back
  • 3x3 snap down design adjusts the sizing to fit small, medium and large sizes (approximately 7-35+ pounds)
  • Trim, snug and comfortable stretchy tabs provide a custom fit
  • Waterproof insert stopper prevents leaking at the tummy
  • Diapers are bundled with two inserts: a newborn insert for newborns and a one-size insert for your older baby
  • Slot cover protects your baby from wetness
  • Pocket style lets you choose the absorbency to fit your baby's needs. When your baby outgrows the newborn insert, it works as an overnight booster or as extra absorbency for heavy wetters

Have an older version? When the elastic is losing its stretch order, a refresher kit here!

NOTE : In an attempt to support international retailers who work hard to support their local customers, the manufacturer of bumGenius! will not allow us to ship internationally as of September 10, 2007. We can still ship most other products internationally!


From the manufacturer: "One-Size: 3x3 snap-down design adjusts the sizing to fit small, medium, and large sizes (approximately 7-35+ pounds)."

We believe, along with most other parents, that these one-size diapers don't start fitting until 12-13 lbs and/or 2-3 months. However, they do seem to fit through potty learning for most toddlers.

How to prepare for first use

We recommend washing and drying your bumGenius One-Size Pocket Diapers one time before use. For pocket diapers, remove inserts from the pocket before washing. It is not recommended to dry diaper covers on high heat. Low heat or line drying is best. That's it!

    About Cotton Babies

    Cotton Babies began with $100 worth of product in a tiny green milkcrate stored on a shelf in our kitchen. It grew from there to a bookshelf, then a closet, then a bedroom, then a basement and finally, the business exploded into commercial space.

    Today, Cotton Babies is a privately held market leader in the juvenile product industry and a diverse retailer, offering everything a family needs to take care of their baby. Our primary focus is cloth diapers, but we also offer a wealth of other products designed to make parenting easy!

    Where are we?
    Cotton Babies is located in St. Louis, Missouri. Our online and administrative operations run out of a large campus located in Fenton, Missouri, a community that lies on the southern border of St. Louis County.  Additionally, we have a retail store serving the St. Louis area located in Town & Country, Missouri, and a manufacturing facility located in Denver, Colorado.    

    Our owner, Jennifer Labit, cares deeply about growth of the cloth diapering industry. She was the founding chair of the Real Diaper Industry Association, a 501(c)6 trade association created for cloth diaper retailers, manufacturers, diaper services, media and other parties with an interest in the cloth diaper industry. Under the leadership of a diverse board, the RDIA is healthy and growing rapidly as they labor to expand consumer awareness of cloth diapers and support industry needs in an exploding cloth diaper market.

    Social Responsibility
    Today, Jenn is focused on raising the standard of excellence in the baby industry through creative designs and unique marketing approaches. Her goals are continued growth of the cloth diaper category in an effort to reduce waste and raise the standard of living in areas her company has influence. Cotton Babies reaches out to local families through targeted outreaches designed to get cloth diapers in the hands of the less fortunate. Cotton Babies also provides cloth diapers to thousands of missionaries through the Diaper Grant program.

    Corporate Philosophies
    In an industry filled with abundant diversity, Cotton Babies endeavors to build bridges with people, not walls over differences. We operate our retail stores under the premise that "every mom leaves our store feeling like a good mom". When designing new products, our goal is always to support parents at every point on the spectrum and offer a variety of customizable options to fit their unique needs.

    Cotton Babies wants to see cloth diapers in every home across America. Our owners created the bumGenius brand, the Flip Hybrid Diapering System, and Econobum. Each brand is designed to reach out to a different unique market segment. Today, Cotton Babies' brands are sold through thousands of independent juvenile stores worldwide and major retailers.

    Cotton Babies wants to make it easy for more families to use cloth diapers. With bumGenius, Flip and Econobum, we've increased accessibility to cloth diapers by recognizing families at different places in life. We believe that every parent and baby is unique. These distinctions demand a variety of options.
