It's Not Terrible
This mask is huge and covers the entire lower half of my face... and I normally need large masks to fit my big head.  It's thin, so that's nice.  But it weirdly gets all hot and wet from the condensation of your breath.  I will wear this mask when I go shopping or for other short trips because it's not bad, but I would not wear it for longer than an hour or two.
