Bumgenius boosters are made from 2 layers of ultra absorbent microfibre terry. Each pack contains 6 boosters.
A booster is used when your baby's nappy needs to last longer than normal, including overnight, in the car, nap time or for heavy wetters. They are also perfect to use in one-size pocket nappies when they are on their smallest setting.
Microfibre should not be placed against your baby's skin, use under other fabrics or inside a pocket nappy.
