A patented tri-lens design that provides an expansive field of vision. The side windows increase your field of vision but does make it a little larger volume but don't worry !! An average person can clear their mask 4-5 times on one exhalation !! Features a double-flanged silicone skirt for an excellent face seal.
This mask fits a wider face. Fits men really well but usually too wide for ladies. Very nice clearance for those with a more predominant forehead or larger nose.
