This cover was designed for the perfect fit, especially for skinnier babies.  Thin and trim, especially great for those skinner babies.  A gusset with lycra binding wraps around baby's leg with less bulk and no gaps.  It also allows the close fit without leaving marks on baby's soft skin.  It is made of 1 layer of PUL (wipe clean) interior.  Works with flat or fitted diapers.  Comes in White and four retro colours with dot patterns.
