Here's how the best-selling Fuzzi Bunz diapering system works: The waterproof outer barrier keeps wetness contained. The soft microfleece inner layer gently touches your baby’s skin, pulling away moisture and keeping your baby rash-free, dry, and comfortable. The microfleece is made of 100% Polyester and is custom-milled. The unique, patented pocket-style opening enables you to customize the absorbency to fit your baby needs. Stuff the pocket with inserts, a pre-fold, or even a hand towel! The updated top-stitching circles the top of the diaper and the tabs, providing reinforcement and demonstrating our commitment to making high quality diapers that hold up wash after wash. The larger, square tabs hold the diaper in place to prevent sagging and provide better grip during diaper changes. The stretchier elastic around the legs provides maximum comfort for baby. The leg casings create “mini-gussets” to keep messes contained and leaks at bay. The adjustable snap settings grow with your baby and enable you to adjust for your baby’s waist and leg sizes. The variety of sizes – including preemie, small, medium, large, petite toddler, and extra-large – ensure that Fuzzi Bunz properly fit your baby. The wide-array of color choices makes diapering fun!
