I've been satisfied with my modular (flip-up) full face helmet for long, multi-day rides. Here is WA State, the State Patrol Motor Officers all use them. If that type of helmet wasn't "safe," you'd bet that they wouldn't be using it day-in, day-out; hundreds of miles per shift. All that said... find what fits you...DOT plus Snell Rating would be highest rating... and makes you comfortable for the long haul (fitment... no pressure points... good ventilation... low wind resistance for reduced wind noise. Good luck with the hunt!
