With the Flip Stay-Dry Diaper cloth diapering has never been so easy! Just toss the used insert into your diaper pail, replace the insert with a clean one and reuse the cover. Wipe the inside of the cover out and use it over and over again. The Flip All-in-two (AI2) uses form fitting elastic to prevent leaks and there is no stuffing involved, the absorbent layer goes directly against the baby's skin. Choose between a one-size Stay-Dry Insert or a one-size Certified Organic Cotton Insert, or use with any prefold diaper. Fits most babies from 7-35 pounds.
