I WOULD NOT RECOMMEND THIS MASK AT ALL. I am going to return it, but unfortunately I have to order a different one, so I won't lose a couple days of not having one.
1. the clips on the side come off during sleep
2. Its clunky, and hisses from the way it's made, air escapes constantly.
3. I have not had a restful sleep since I bought it, due to the noise and clips coming off.
Now the band that goes around the head is the best feature. its comfortable, and doesn't leave the huge grooves in your face as some of the others.
