this review title is: just ok and the content is: wish the elastic cord was wide and flat instead of just elastic string it hurts after awhile because it feels like it s cutting into skin leave a red line across head because it s so thin needs to be flat strap it works but it fogs up since it s such a good seal also elastic stretches out permanently over a few days of wearing it so you have to keep tying knots in it to shorten it back up if it s too loose it doesn t seal so it has to be snug and of course that causes it to hurts over time where the thin elastic cord is lying across your head.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.
