Arai's quality is so singularly advanced that it reaches the world's highest level of racing, a place so technical, so demanding, that most other helmet makers can't even imagine it, let alone compete in it. We're talking about Formula One auto racing.
(Arai holds the unbelievable distinction of being chosen by more than half of the F-1 grid! Including the new 2006 world champion and three of the top-five drivers.)
One of the benefits of Arai's F-1 involvement that has come down to motorcyclists is that we learned the best way to ventilate a helmet is to pull the hot stale air out, rather than trying to push new air in. (This led Arai to introduce the world's first diffuser-mounted motorcycle helmet, the RX-7 series, one of our most-copied features ever!) And now we've brought this technology and comfort to an open-face helmet!
Arai's EPS liner is like no other, comprised of several material densities molded into a single piece. Arai pioneered this technology more than 20 years ago and is still, to our knowledge, the only helmet offering a single-piece hybrid liner and its unique benefit: the direct-fused contact area that each EPS cell shares with it neighboring cells creates a mutual support - as one is crushed under impact, the surrounding cells assist with the energy absorption. (Liner pieces that are simply fitted or glued together cannot rely on such a high-level support bond.)
NOTE: Besides the protective aspects of Arai's shell material and single-piece EPS liner construction, there is a major comfort bonus for you, the rider: Arai's Snell-certified liners so soft and comfortable they can actually conform to your head shape within several days of continued use, minimizing "hot spots," allowing the most comfortable fit in the best possible (smallest) size that fits you. (So don't loan your Arai to somebody else, or it just might come back fitting them better than you.)
These days there are almost as many "revolutionary" shell-construction materials as there are new helmet brands. Who do you believe? Arai's decades of experience, research, testing, comparison and evaluation have led Arai people to conclude that fiberglass-based construction does the best job of performing a motorcycle-helmet shell's main job - spreading and dissipating impact energy through strength, structural integrity and impact-flexibility. The Ram-III's clc (Complex Laminate Construction) shell utilizes Arai's proprietary aerospace fiberglass technology to achieve a strong, flexible shell in a lightweight package.
