If you ride both mountain and road bikes, do you really need two different helmets? Unless you strive to make a different fashion statement with each bike, the answer is most likely "no." But, while you want a well-ventilated, lightweight helmet for the road, you also know that durability is paramount for trail riding. Mavic developed the Plasma Helmet to satisfy the inner roadie as well as the trail rider.

More important than versatility however, Mavic devoted itself to making the Plasma the most comfortable helmet that you'll try. First, Mavic looked at optimizing the actual shape of the helmet. It conducted cranial mapping tests to make certain that the Plasma closely matches typical head shapes. Additionally, Mavic identified the not-so-obvious pressure points and contours, and made the interior shape of the helmet consequently flow along with the curves of the skull. But, even with a mound of data, there were still variances. This is where Mavic's Ergo Hold System comes into play. It allows for as much as six centimeters of one-handed, on-the-fly size adjustment. For the final touches on fit perfection, as well as excellent moisture management, Mavic also included its Ergo Fit Pro Pad. At first glance, it might not seem like much, but the Ergo Fit Pro Pad is a low density, open cell foam that wicks water away from the skin and transports it to where it can quickly evaporate.

After guaranteeing comfort, Mavic took a hard look at the aerodynamic and durability aspects of the exterior. First, Mavic fashioned a sleek, low-volume profile. Then, looking towards ventilation, Mavic developed the Ergo Protec Alutex reinforcement. This technology makes it possible to build in huge frontal ventilation ports without compromising any of the helmet's crash protection. So, not only are you riding cool and protected, but the aggressive shape enhances your aerodynamic position. Finally, for added versatility and well, a little trail fashion sense, Mavic included a removable visor and plugs.

The Mavic Plasma Helmet has been given reflective highlights in order to increase your visibility to motorists when you're caught out after dark. The helmet is available in the sizes Small, Medium, and Large and in the colors Black/silver metallic X, White/red, and White/white.

Great helmet!

  • Familiarity: I've put it through the wringer

This is a great helmet. Venting is more than adequate. One-handed open and close size adjustment is a great feature too.

  • Familiarity: I've used it once or twice and have initial impressions

I've never really spent the money to get a good helmet, but with more and more miles under my belt (and more and more crash scars), I decided it was time to spend a little cash to get a better helmet. I mtb and cycle, so I wanted a helmet that I could use for both. In addition, I wanted a helmet that actually fit my smaller head (one that didn't come with polka-dots or animal tail off the back). When I first put on this helmet, I could easily adjust the fit and was instantly in love. It's light weight & well fitted. An added bonus are the ventilation holes.
