Kushies Washable Diaper Liners are ideal when you need additional absorbency. A diaper liner can add much more absorbency without the bulk. Kushies Washable Liners are made of three layer of 100% premium cotton flannel for an ultra soft feel against baby's skin. Use a diaper liner for heavy wetters, nap time, overnight or any time you need extra absorbency. Kushies Washable Liners work with all-in-one, fitted or pre-fold diapers and are machine washable.
