ABSORBENT AND WATERPROOF: The Esembly Cloth Diapering Bundle includes three ultra-absorbent organic cotton Inners and one recycled waterproof Outer. The Esembly diaper is made of 2 parts, the Inner provides the absorbency, and the Outer layers over the Inner to complete the diaper. BLOWOUT PROOF: Disposables are notorious for messy leaks and blowouts, Esembly’s two-part diaper ensures no inconvenient leaks. If anything is to sneak past the Inner, it gets caught by the Outer. The ultimate in diaper containment! ORGANIC AND RECYCLED: Esembly Inners are made of 100% certified organic cotton As for the Outers, we’re turning trash into treasure! STANDARD 100 OEKO-TEX certified and made of 100% post-consumer plastic bottles, Outers are free of lead, BPA, PVC, and phthalates, making them perfect for your baby's sensitive skin. LANDFILL-FREE and $ SAVING: Instead of going through endless packs of disposables (6500+ if we’re talking numbers), with Esembly you only need 20-24 diapers Inners, and 6 Outers (in each of the 2 sizes) from birth through potty training. This not only saves the planet from diaper waste but saves you money too! EASY TO LAUNDER: Afraid of the laundry? Don’t be. Inners are designed by diaper laundering experts! Wash them twice per week following Esembly’s easy and effective 4-step instructions. For best results, launder with specially formulated Esembly Washing Powder (sold separately).
