This Review Title is Waterproof? Not really. and the content is: It may be water resistant but it’s not waterproof. The elastic edge allows a great deal of water in around the edge, so if you want to keep your hair dry while showering, keep your head out of the shower spray. It’ll work great then..There are other information for this review, one is This reviewer did purchase it and the other is 1 people think this review is helpful.
