Tough HeadwearTough Headwear Neoprene Half Face Mask Cold Weather - Half Ski Face Mask - Men's Winter Face Mask for Outdoors, Motorcycle

I have glasses will it fog them up?

I tried washing the mask in Tide but still cannot the neoprene odor out. Any suggestions?

the picture looks like it covers the sides and back of the neck, but the view on the bottom looks short on the sides and back, so is the picture true?

i measured the band size from the back of my neck to the tip of my nose and its 21 3/4 inches, so will this fit correctly or will it be too big?
