Very good product to protect the pillow, really waterproof, the downside is that it is so tight that when we put the head on the pillow means a small air exhaust (the pillow empties his air) and that it inflates very slowly, making it lose the softness of the pillow. I have a pillow of down, maybe a synthetic pillow would have more strength to regain its shape in that one changes position. I think this is an important criterion to know before you buy a raincoat protects pillow
