Is the mattress protector waterproof?

In order to stay breathable, the Endy Mattress Protector is highly water-resistant, but not entirely waterproof. It provides the perfect amount of protection against spills and every day moisture—but we don’t recommend taking it for a swim.

Protection would not be adequate against extreme cases of liquid contact with the mattress protector, especially over extended periods of time. We never recommend using your mattress outdoors.
