just ok [SEP] 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
