Waterproof but breathable cover/wrap (4 -15 kg according to child’s proportions). Can be adjusted to Small, Medium and Large size thanks to the snaps. The snaps are underlaid by suedecloth and the Hook & Loop by second PUL layer. All this to prolong the product lifespan and for its better performance. Material: 100% polyester (laminated with polyurethan), fleece hem. The fleece hems are very sensitive to child’s legs and tummy - no marks on the skin. The fleece is also a great insulator - no leaking. These covers have medium-wide shape and are suitable for squares, prefolds, or almost any other cloth nappy (ever our Maxi Night Nappy). They are specially adapted to our SIO system. Learn more about maintenance.
