You get what you pay for!  The Best!
Made in the USA and absolutely the best for my xl head and face.  This is the best mask I have purchased.  The adjustable ear and neck band allows the mask to be pulled down and remain secured around the neck.  The craftsmanship is impeccable and the fit is so comfortable.  My glasses rest on the nose piece allowing a better seal.  There is a pocket for a 5 layer carbon filter (not included).  If you want the best, this is the mask.  I heartily recommend and will buy again.
