Great price. Love the look. Vents work great. My head measurement was 58cm. I bought a med according to size chart, after a little help from tech support. It arrived within a few days. It was a little snug for my taste. I might try a large if I buy another one, and just use that one for my passenger. I wish I would have known that it didn't come with shield that it was pictured with. I would have bought one at the same time.To quote FOREST GUMP " that's about all I got to say about that".
