The last time me and a buddy rode, it was hot, humid, and miserable, and our regular dirtbike helmets were like swimming pools. After that ride I vowed to find something different. Just picked up a Fox Proframe MIPS helmet, and WOW what a difference. I'm old and slow, and would not recommend this helmet to anyone doing MX, high speed desert racing, or any Dual Sport on road stuff, but for woods riding it's incredible. Feels and fits like a bicycle helmet, so it doesn't have all the comfort padding, but it's so light and ventilated I can't get over it. The top downhill bike riders are using it, and they are faster than me at times, so I figure it's OK for my use. Anyone else use one of these? If not, look at your riding style, and check it out. Note, not affiliated blah blah. Interest lies in if I am the only one trying this out on a dirtbike.
