Use this cloth diaper with a diaper cover (not included). Workhorse diaper is made of 100% cotton prefold fabric in a fitted diaper shape with snap closures and a built in flap style doubler. It is flat when brand new, but please wash it before using it and it will shrink to the proper size and quilt up like the pictures. Newborn and small have 6 layers in the flap and medium and up have 8 layer flaps, which is age-appropriate layering. Did you ever wish your lovely prefolds were shaped like a fitted? There is no better diapering fabric than the cotton prefold fabric. It washes so easily and wears so well. No polyester stink, no repelling, no special detergents are needed for 100% cotton diapers. The snaps are covered by the cotton fabric inside so no snaps touch baby. The flap style doubler is sewn inside in the back only for quick drying. Designed by Karen and made exclusively for Green Mountain Diapers. This is an economy fitted with great low price and no confusing adjustments which create additional bumps and lumpy places. It’s not fancy, but it does the job really well at a great price. Five sizes for a great fit. Newborn: 5 – 12 pounds, Small: 9 – 14 pounds, Medium: 14 – 24 pounds, Large: 21 – 30 pounds, XLarge: 26 – 38 pounds.
