A world-class fit – thanks to the Free Flex design with stretchy sides and back and self-adhesive fastening tape. Libero Comfort has the Nordic Ecolabel – a guarantee that the diapers contain no lotions, ointments, moisturising creams or perfumes. You will recognise the packet by the green strip and the number 4. We continuously work to minimise our environmental impact at all stages, for example through our diaper manufacturing processes, our choice of suppliers, materials, designs, fit and packaging So whichever Libero diaper size you choose, you're making a sound environmental choice.
