Comfort: 2/5 -- Doesn't fit well and keeps sliding down no matter how tight I tie it at the back. The cloth is rigid and folded in an awkward way. The chin strap only works to pull the mask down further. When pulled tight at the back the aluminum nose tab presses against the nose. When I try to put my helmet on the mask will slide down so it needs some adjusting. Value: 4/5? -- It is meant to last a minimum of 6 months assuming it is used every day and washed once a month. It only costed me $60. Effectiveness: 2.5/5 -- There are always gaps no matter how I wear it. Exhaust fumes will always get through. But when I put my helmet on it kinda presses it against my cheeks and closes the gap under my chin/neck. It does seem to filter out exhaust fumes to an extent. Appearance: 4/5 -- I like the way it looks Overall: 2.5/5 -- Could have been much better with a strap that goes over the ears. It seems to work better if I put the chin strap around my head and over my ears. Not too difficult to put a helmet over and then pull the fabric up.
