The diaper cover consist of two layers, 100% organic cotton jersey on the outside for a comfortable feel. The material inside, a polyurethane laminated polyester fabric, keeps the pants leakproof and also lets air through to your baby's skin. The covers have a practical hook and loop fastening, effective leg cuffs and an elastic inset at the back.
 This cover keeps baby dry, but is breathable and still allows air circulation.  The soft loop makes for easy diaper changes and eliminates the use of pins.
