Bumgenius are an award winning US brand of reusable nappies.  Renowned for their bumgenius V5 pocket, bumgenius elemental and their flexible Flip system, they aim to make washable nappies as easy to use as disposables.  Over the years Bumgenius has learnt that many families have children struggling with incontinence issues. To address this Bumgenius has created larger nappies to fit from older child to small adult. Big was designed with a child in mind and will fit from 35-70lbs. You can also get an even larger nappy called BIGGER which was designed to fit an older child, teen or small adult 70-120lbs

Bumgenius Big cloth nappy is a larger cloth nappy for big toddlers fitting 35-70 pounds. 

The nappies are made with super soft stay-dry lining that wicks moisture away from skin. Gentle leg elastic and waterproof outer cover prevent leaks.

You can stuff any insert inside the pocket to customize absorbency and inserts are sold separately.   You can use 50cm terry squares or cotton prefolds . Both fit well inside this nappy.  But we recommend the AppleCheeks 2ply bamboo inserts which work very well inside the nappy.

  • Proprietary elastic designed specifically for cloth diapers
  • Stretchy stay-dry lining is super soft , wicks moisture away from skin, and provides a trim fit
  • Waterproof outer cover with insert stopper at waistline prevents leaks
  • Durable plastic snaps
  • 3×3 snap down design adjusts for customized sizing
  • Trim, snug and comfortable stretchy tabs provide a custom fit
  • Pocket accommodates inserts for customized absorbency
  • Legs: 7.5\”-22\”
  • Waist: 14\”-30\”

Oeko-Tex Standard 100 certification indicates that bumGenius diapers have been stringently tested and are free from harmful or problematic substances.

Washing – wash between 40° to 60°.   Washing and Care – please read carefully our full ‘washing and care instructions’.  All nappies and wraps must be washed according to our care instructions otherwise the manufacturers guarantee will not be valid.  All new nappies must be washed before they are used.  Please note that when buying a large number of cloth nappies you should just wash a few in the first instance, and check you are happy with your choice, as I cannot refund on used or washed nappies. This nappy can be tumble dried on a low heat, however it is advisable to only tumble dry occasionally as it does shorten the life of the nappy and of course cost you more. Do not use Ecover washing powder or liquid with your cloth nappies
