The description mentioned that cooling fabric on the inside, and this turned out to be a real thing! the masks are comfortable, sturdy and look great. They may be a little small for regulations, but mine cover my nose and go just below my chin, so should be ok.
I got this to wear in a situation where I didn't feel surgical quality protection was necessary, but I wanted a shield that looked nice and did block moisture as I exhaled. These are just exactly that. No extra filter can be installed, but you feel more secure than with, say, a scarf. The metal "shaper" at the top could be longer (I have a big nose and wear glasses), but these are good for the money.
