Very safe and useful.
The hat seems well made and is similar to summer hats I always wore. The hat did come folded in a padded envelope and had a pronounced crease. Now I see that the instructions online say to use a hair dryer. I may try that but the crease is already softening with time. I turned the hat inside out and left it and that helped. I still use a face mask but this protects the eyes and is a strong extra layer for the nose and mouth. I might see if one is made with UV protection for summer.
