Simple 3 x 3 snap downs adjust to your baby's rise then hook and loop fasteners let you get a trim fit just for your baby. Designed with fit and function in mind.

New features of the 4.0: 1. Now accommodates even larger babies! Better yet, the diaper still fits small babies too. 2. All new hook & loop closures (also available in refresher kits) 3. Accessible, easily replaceable elastic. All elastic tack-points are now visible from the inside of the diaper.
