Anti pollution mask

After two years of cycling in Belgrade I have inhaled enough smog for the rest of my life so this is my newest cycling gadget! Unfortunately, I can’t pass as a bike ninja (someone who is riding their bicycle under low visibility conditions, without a headlight or taillight) as I have appropriate night lights attached to my bike, and I’m wearing all those fluorescent yellow stripes around my ankles. Though, it could be useful during a future anti-government demonstration, and I will have to test it on a ski holiday also.
