At Charlie Banana, we're all about caring for your baby and our planet at the same time. Our extra-absorbent reusable deluxe inserts are designed with multiple layers of absorbent microfiber, one layer of super-soft fleece, and our signature edge-to-edge softness to help protect your baby's delicate skin. We use only safe materials, rigorously tested for harmful substances, and are certified under Standard 100 by Oeko-Tex*. In the box, you'll find three reusable deluxe inserts (newborn/booster) to put in any Charlie Banana diaper. The perfect proportions for our XS size setting, use one or two newborn reusable inserts. And as your baby grows (and for bigger sizes), pair it with our One Size for enhanced absorbency! *Safety tested and Standard 100 by Oeko-Tex Certified, 4.8.22
