Just ok.
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.
