Seirus

#1 selling face mask in the world. Seirus patented design prevents blow-back, by channeling your exhale down and away from you so you do not fog up glasses, goggles or binoculars. 200wt performance fleece neck keeps you warm by keeping the wind off your skin and retaining your body heat. Adjustable Velcro closure makes this an easy on/off piece and it rolls or folds easily for storage in a pocket or pack when not in use.
