Easy to fit

This nappy takes no time to put on the baby but it doesn't last too long

Very Smart

I only tried this nappy for the print with the foxes. But I went back to order more after. Its very slim and fits so well around the legs.
I love all in ones for how easy they are to use. This one has a really long tongue which is a good shape for folding inside the nappy.
One thing that is unusual is how the poppers are on the front, they are the opposite way around compared to most nappies which the male poppers across the front and the female poppers on the tabs.
