when I first saw the bag that the protector was in , I was surprised that the protector was terry  cloth. It didn't seem like the best plan for such an item. I have not opened the bag or anything .  It's un-used & I intend to return it .
I just did not want to take a chance w/ a wet bed!
                                           I ordered another one also which seems much better.  I'm giving it 4 syars because the pad was packed completely secure and in a heavy-duty plastic bag.
