Let me get the bad out of the way.............simply because no helmet is perfect! These helmets are not reflective of your size going by their chart! Plain and simple and I am being honest, if your borderline two sizes, go up to the next size! if your bottom of the size range your fine! Reason for my 3 stars! Now we have that out of the way! This helmet has every feature one could want in a modular. The helmet has the fighter pilot style flip down sun visor! Now this is just plain and simply COOL! It works too! The shield has great peripheral vision and does not fog! Another big plus to keep you from sinking more money into a fog insert. The ability if the helmet is slightly big to add air with it's built in pump and bladder system is without a doubt, genius. The shield even breaks down easily with no tools to make it into a 3/4 helmet without doing away with the sun visor which retracts into the helmet! The pull out liner can be washed too. Really my 4 stars overall is not fair.........nothing deserves a 5 but this is a 4.75 on my rating scale. Really nice helmet for the money. Only thing close to this is a Schuberth which cost 2.5 times the Scorpion!
