EUC set of 5 Esembly size 2 diapers covers fit over size 2 Esembly inners (18-35 pounds). All snaps and elastic in like new condition. A waterproof cloth diaper cover that layers over the absorbent Inner to make a blowout-proof diaper. Can also be used on its own as a reusable swim diaper. The Outer snaps on your baby right over the Inner cotton diaper. The Outer is the part of the cloth diaper that provides the containment, if anything sneaks past the Inner you can rest assured it won’t go beyond the Outer. Outers come in two trim-fitting sizes and are designed to grow with your baby. Two rows of snaps at the waist allow you to adjust the size of the waist independently from the openings at the legs. This enables you to get a perfect fit on babies with big round bellies and skinny legs, and vice versa. Even better, Outers can be used as reusable swim diapers! Simply put just the Outer on your baby (with no Inner or absorbent material inside) and you're ready for the water. Outer cloth diaper covers are not just cute, they're innovative! The exclusive fabric is made of recycled plastic bottles and its unique structure allows for optimal heat and vapor transmission (which basically means that they provide maximum breathability, keeping your baby comfortable longer).
