Scorpion seems to run a little small, I really do like this hemlet a lot, because of price, comfort, quality, and the secondary flip down smoke visor. Great buy for the money.
The EXO-500 has a reputation for giving the best bang for your buck utilizing such features as: KwikWick II® liner for extreme moisture control, AirFit® cheekpad system for a custom snug fit, drop down SpeedView® sun visor, and Aero-Tuned Ventilation with 3 intake vents and 6 exhaust vents for maximum breathability. The EXO-500 is the industry standard for technology and style - and priced to fit just about any budget. From the daily commuter to the seasoned touring rider, the EXO-500 is a premium helmet at an unbeatable price.
