Your investment in these small wet bags goes a long way. Don't think of it as a nappy bag, but as an all purpose parenting bag. Designed for storing cloth nappies, they can also be used for make up, 'no leak' sippy cups and reusable wipes, and are also ideal for organising your hospital bag and luggage. These small wet bags can hold 1-2 nappies and measure 22 x 27cm.

Our small wet bags are made from the same material as the outer shell of our reusable nappies. So, just like a nappy, they are designed to keep wetness in, but they won't tolerate being soaked. While they are perfect for storing dirty nappies, damp wipes, swim suits in a towel etc., if you use them for something really wet (like rinsed, unwrung CSP, very wet wipes, or a swimsuit that's not been wrung out) then they will wick moisture - just like a nappy.
