All of our nappies are a ONE SIZE FITS MOST design. That means our cloth diapers are fully adjustable so you only need to buy one size nappy! Simply adjust the press studs on the nappy as your baby grows. The outer is made of polyester with 100% WATERPROOF PUL, so no need for additional covers!The inner is 100% white BAMBOO charcoal fleece and is soft against baby's skin. It is naturally antibacterial, mildew resistant and provides great ventilation. The EASY-TO-USE POCKET DESIGN means the insert sits inside the pocket, allowing for speedy drying (as the nappy has 2 parts) and less irritation for your baby's skin. EACH NAPPY COMES WITH 1 BAMBOO CHARCOAL INSERT (3 layers of microfiber & 2 layers of bamboo charcoal fleece). Each insert is fast drying and highly absorbent. There is even room to add an extra insert to boost nighttime absorbency.Explore from our collection of award-winning bamboo nappies, that have won "Best Reusable Nappy" in Australia multiple times.
