FOG WIPER for Firefighter Mask
FIREFIGHTER MASK NOT INCLUDED!  This fog wiper is a manual device that allows the user to slide a wiper/magnet on the outside of the glass, causing an inside wiper/magnet to move in unison and wipe off fog. This product works with all types of firefighting airpacks (e.g. Scott). Wide-i fog wipers for swimming goggles, scuba diving & snorkel masks, snow & snowboard goggles, airsoft & paintball masks, and professional dive helmets, are also available at Amazon. Note that the unit price (quantity=1) is for a single pair of magnets.
