Cool, that is great to read. I had ordered the bandana masks from Rocky Mountain ATV that had vents. They worked relatively well, but the white paint on the bandana started flaking off after the first hand wash. I am sure inhaling paint chips from China was much worse than breathing dust.The wife and I finally got around to using our Wolf Snouts yesterday while riding with a group of 20 or so other vehicles. Everyone kind of looked at us like were crazy but after the first several miles in the dust they all wished they had some too. After 36 miles of riding there was no dust up the nose. Our ears were full of dust, our faces were covered, but no dust inside where it counts. Great when riding with others.
