Are Reasonably Comfortable [SEP] These hold well during use and don't pull too tight on the nose.<br />However, they are maxed out for me (last hook on each side) for comfort<br />and wouldn't want them any tighter. (my head - thick hair - 22" around)<br /><br />Even when pulling mask down around the neck, IF careful, stays connected.<br />But if pulling down without care, of course the strap is disconnected.<br />The silicone seems durable enough and doesn't pull my hair.<br /><br />This isn't a perfect situation, but I've not come across one that is.<br />SOo = 4 stars
