Thirsties Duo Diapers are the newest addition to the market, each Duo diaper comes with an absorbent insert made or a micro fiber/hemp combo. Duo diapers come in two expandable sizes, these cloth diapers last for a long time yet fit a baby snugly at any age. Thirsties cloth diapers, diaper covers and inserts are fordable and made entirely in the USA, including the fabrics. We really like Thirsties products for their quality, leak proof design and great prices. The company also thrives to stay green in their production. You can choose from all in one diapers, that have a pocket for extra inserts, or Fab Fitteds - Thirsties fitted diapers which require a diaper cover. Thirsties covers come in two styles: Duo Wrap which is a one size cover and the original Thirsties Diaper Cover offered in sizes Extra Small to Large.
