Ignore the 509 train your about to get with this thread.. I have tried them all. KLIM is the most ventilated.... BRP has the lightest... But the most comfortable helmet I have worn to date out of all of them is the FOX V4 carbon fiber helmet. SOOOOOOO much nicer than the rest! You dont HAVE to get the carbon fiber one but seriosly... Anyone that has the chance... try that baby on!
