It is a good mask for larger faces or large head sizes. Nice stiff front of the mask. The only issue I have is that the lower portion under my chin catches my beard like velcro and pulls it down off of my nose. I do not have this issue with any other kf94 masks such as the bluna, Dr Puri, or the BOTN. Not sure why this particular one has this issue but I have tried several and always have the same issue.
