Kinder Cloth Diaper Co. Lightweight 4-Layer Bamboo Inserts absorb quickly with less bulk. Because our bamboo inserts contain absolutely NO microfiber filler layers, they're less prone to compression leaks and more trim on your baby's bottom! Our inserts work great on their own, but are even better when used as boosters with another natural fiber like hemp or cotton.  4 Layers of Bamboo Terry Lighter weight and slightly less absorbent than our standard Kinder Bamboo Insert. 100% Bamboo Terry NO Microfiber Two snaps for easy attaching to our pockets, covers and other inserts. Thin profile. Less bulky. Approx. Size (pre-washed): 13"x5"x0.125" Wash multiple times to reach maximum absorbency with our natural fiber inserts. When you receive your inserts, be sure to wash with warm water and dry on low heat. Inserts are made of natural fibers, therefore shrinkage is normal and to be expected.
