Thanks for the input...I like Wolfsnout better too!These are great masks. I like them because I can easily lower it onto my chin when I do not need and push it back up when I do. They are easily hand washed too. I also have the RZR masks however they are a PITA from an operational standpoint. There is no sliding them up and down your face. They do filter better due to the replaceable charco elements however not worth the hasel.
