All in one nappies are very easy to use. The absorbent inner is attached to the waterproof outer cover, so these nappies are a one piece wonder! There's no hunting for the inserts and the absorbent pads flap open which assists with drying. These nappies are often not quite as good at containment as a two piece system nappy, but they still perform better than a disposable. Perfect for childcare or relatives to use, and a great addition to the change bag.
