Thirsties Diaper Covers secure with durable hook and loop for a perfect and secure fit at every diaper change. The specialty waterproof fabric is extremely pliable and comfortable for your baby's delicate skin. Leg gussets provide advanced leak-proof protection and bindings are super soft against baby skin. The x-small size features an umbilical cut out for your newborn's comfort and all sizes offer convenient fold-over laundry tabs to protect your hook and loop closure's from trapping lint in the wash. The generous cut of Thirsties Diaper Covers offers a superior waterproof exterior on any type of flat, prefolded, contoured, or fitted cloth diaper. In order to achieve optimal breath-ability and hassle-free washing, Thirsties Diaper Covers are made from a single layer of polyester laminate. Want to get away with fewer diaper covers in rotation? The laminate that lines the inside of the soft polyester can be wiped clean between uses, then washed in your washer once thoroughly soiled. Thirsties Diaper Covers provide a roomy fit and are ideal for chunky babies, over bulkier diapers, and nighttime systems. For trimmer fit and for tri-folding prefold cloth diapers, we recommend Thirsties Duo Wraps.
