Portacrib waterproof pads are designed to protect your babys crib mattresses from spills and spit-ups. These pads come in a pack of 2. They're made from soft fleece, which is gentle against your babys delicate skin. The pads have polyester lining on the top and bottom. Their inner vinyl inner layer acts as a waterproof barrier in the center. These organic changing pads have a quilted lamb pattern that matches any nursery décor. These machine-washable baby changing pads fold up and fit in a diaper bag for portability. Plus, they're non-allergenic.
