For overnight protection, most cloth diaper parents will tell you that the key to maximum absorbency is to use a layered approach with a waterproof cover. For that, the Thirsties Duo Wrap is our top pick. Parents love how easy they are to stuff with multiple layers of “fluff” (aka inserts, prefolds, or flats) and that the cover is waterproof, but totally soft, so it doesn’t seem as harsh as other waterproof fabrics against baby’s skin. You can wipe the wraps clean between uses, and machine washing is recommended every three to four wears. They come in two sizes — one for babies 6 to 18 pounds and another for babies 18 to 40 pounds — both of which offer a tall gusset with three snap settings for an adjustable fit that grows with your baby and works to contain leaks like a total pro.
