I bought an FX-41DS to replace my FX-37DS which was wearing out. I got the hi-vis safety orange - it has been a great choice - the colour is brilliantly vivid and extremely visible. I've gotten many positive comments on the colour (except from friends who ride Harleys....). My FX-37 was an XL, so I ordered an XL FX-41, and the fit was good. PROS: Good ventilation; sun shade is very handy; quick-release strap is an excellent design (easy to use & adjusts to accomodate cold weather balaclavas, etc.); visor is more "squared-off" than FX-37 and works better keeping the sun out of your eyes; very comfortable fit. CONS: The design of the faceshield distorts the bottom of your visual field - you have to tip your head down to see your instruments. Overall, I'm very satisfied with this helmet. PS - if you get the Safety Orange colour, "Quo by Orly Neon Orange 59707" nail polish is a perfect match for doing touch-ups.
