Double Sport Helmets Vs. Full Face Helmets
The best dual sport safety helmets will certainly flow approximately the same amount of air as a committed dirt headgear, because they're basically doing the very same job: Keeping you cool while you do active (and as a result sweaty) off-road riding.
DOT ratings are the bare minimum need in the states, however DOT safety and security testing isn't particularly rigorous, so we favor headgears with either Snell scores, ECE certification, or some combination of the three. For you hardcore off-roaders, a dirt-specific cover (motocross-style, no visor, open ventilation, etc) is completely fine.
If you're mosting likely to ride your twin sporting activity as the excellent lord planned (in the dirt), including one of the most effective twin sport headgears on the market to your collection should go to the top of your listing. Ground-up redesign of one of the most desired dual sporting activity headgear money can buy.
Keeping that being stated, bear in mind that while many trusted helmets include an ECE qualification nowadays, you shouldn't neglect a helmet even if it doesn't have one. Thus, many double sporting activity riders have special requirements when it comes to bike gear, specifically when it comes to safety full face helmets.
