Our diaper is the softest diaper on the market, and as we know you LOVE the styling of our Envelope Cover, we've translated the design to a product that really works! One layer of fine dernier knit and one layer of 100% polyester Canadian-milled mesh allows water to comfortably move through the diaper while keeping any solids, should they occur at an inopportune time, out of the pool. Our diaper is completely designed and manufactured right here in Montreal, Quebec, Canada, just like the rest of our AppleCheeks™ line. And our signature two-size system with a snap at the waist and an separately adjustable snap at the thigh means your little one is guaranteed a comfortable, long-last fit. Size 1 fits approximately 7lbs - 23lbs and size 2 fits approximately 18lbs to 40lbs.
