This water-repellent bag made of PUL material can be used to take a stack of cloth diapers or other things with you on the day trip, or to store diapers before washing. Up to 12 nappies can fit in the bag. '
With double zipper pockets, you can separate clean nappies from wet ones.  The material keeps  liquid and odor on the inside, while still breathing. The bag can be washed at 60 degrees Celsius, so just throw it in with the rest of the cloth diapers. 
 
Wet Bag Go has a bottom that allows it to stand up. It also has double straps to attach around the handle on the baby stroller or on a bar in the bathroom.
