Similar in feel and function to our Diaper Cover, Thirsties Duo Wraps are completely waterproof yet remain breathable, pliable, and very comfortable for your baby's delicate skin. With the adjustable rise you will only need two sizes from birth to potty. Leg gussets provide advanced leak-proof protection and bindings are super-soft against your baby's skin. Thirsties Duo Wraps are a very trim fitting cover and are the preferred wrap for fitted, flats, and prefold diapers. The inside of Duo Wraps can be wiped clean between uses allowing for fewer wraps in rotation and greater affordability. We recommend one cover for every 3-4 diapers in rotation (excluding diapers with waterproof exteriors). Cloth Diaper Care Wash all diapers at least one time before use. Prewash on warm, wash on hot, rinse on warm. Tumble dry on low or hang dry.
