This family-owned Japanese company has handcrafted premium helmets for car racers and motorcyclists for decades. Their latest offroad lid is the VX-Pro4. Purposefully devoid of fancy aero aids or edgy shapes, the VX-Pro4’s smooth, organic shape reduces the chance of the helmet snagging on the ground in a crash, thus reducing the chance of imparting rotational forces to the brain. Using a single multi-density EPS inner liner, instead of dual concentric inner liners of some competitors, keeps helmet exterior dimensions smaller, further reducing torque transfer in a fall. The shell is hand laid-up with proprietary fiber belts, which are designed like a car unibody to channel impact loads most beneficially. As usual for Arai helmets, comfort is simply top-notch. $610 to $750. For more info check out Arai's website.
