The one-size-fits-all (5 to 17+ kg) fitted nappy is a night time nappy as the entire nappy is made from ultra soft and absorbent bamboo and cotton - you could call it bombproof.
Four rows of rise snaps in the front allow for small, medium, large and extra large sizing. Each nappy comes with two inserts which contain a bamboo and cotton mix. One insert snaps in with one snap whilst the other is loose. This gives you the option to place the loose insert in a particular area to target the absorbency.
This nappy is not waterproof, so you will also need a waterproof cover to put over this nappy. As with all night time nappies it is likely you will need to add a booster to increase absorbency to get a full 10 to 12 hours wear.
