Manufacture d'Articles Vélocipédiques Idoux et Chanel has specialized in wheels and rims for decades. But, did you know Mavic has done a bit of "this and that" across the cycling world? It even developed the first electronic drivetrain. In the past few years though, much to our delight, Mavic has turned its engineering talent to apparel and protection, giving us the peloton-ready Plasma SLR Helmet.

Mavic's engineers took a long hard look at designing a helmet that is both lightweight and well-ventilated, yet protective. First, Mavic looked at optimizing the actual shape of the helmet. It conducted cranial mapping tests as to ensure that its helmet shapes closely match typical head shapes. This involved identifying and accounting for all of head's natural pressure points and contours. Accordingly, the interior shape of the helmet consequently flows along with the curves of the skull. And while the helmets are designed around the average shape, Mavic knew that no two heads are the same. So, Mavic developed what it calls its Ergo Hold System. Basically, this system allows for as much as six centimeters of one-handed size adjustment.

For the final touches on fit perfection, as well as excellent moisture management, Mavic has included its Ergo Fit Pro Pad with X-Static. It might not seem like much when you look at it, but the Ergo Fit Pro Pad is a low density, open cell foam that wicks moisture away from the skin for a rapid evaporation. Featured in the material are the anti-stink, X-Static fibers. Although it was developed for industrial and medical products, it didn't take long for commercial manufacturers to see how well it would work in athletic equipment. As a fiber with a layer of 99.9% pure silver, X-Static keeps odors to a minimum, while reducing irritating static.

With your head comforted on the inside, Mavic took a hard look at what it could do for the exterior of the helmet. First, Mavic fashioned a sleek profile that has a low-volume construction. Then, looking towards ventilation, Mavic developed its Ergo Protec Carbon. This material makes it possible for Mavic to build in huge frontal vents without compromising any of the helmet's crash protection. Additionally, the aggressive shape aids in aerodynamics, while channeling the comforting wind through the vents. Finally, Mavic included reflective highlights in order to increase your visibility to motorists in low-light conditions.

The Mavic Plasma SLR Helmet is available in the sizes Small, Medium, and Large and in the colors Black, White/black, and Mavic Yellow/black.

Do you have the weight specs. On this helmet ? Is it true the sizing on these helmets run small? I measured in @ 22 1/4inch. So I was thinking of the medium. What's your recommendations on size? Thanks.

Hey JT. This Helmet in a size medium weighs 285 grams.

At 22 1/4 inches, a medium will be a perfect fit for you.
