enclosed my review of the product. A video follows a little later (at present I can not adjust at Amazon).
In the commentary but one can ever copy the link to my YouTube video and then watch this.
The neoprene face mask is very well made. No loose threads or open seams I could find. The range for the nose is completely open and the mouth small holes. Through both one can breathe well. The mask can cover because it is extensible and can be adjusted on the back too easily. Rich they do not. Is it on the head she slipped barely and keeps you warm.
Anyone looking for a face mask for the winter can look at these times.
