Race Protection.

Toss Mavic into casual conversation, and it's naturally going to revolve around wheels and rims. After all, it's what Manufacture d'Articles Vélocipédiques Idoux et Chanel has specialized in for decades. But, Mavic has had its French paws in everything cycling, even developing the first electronic drivetrain -- Mavic has even branched out into manufactured ski edges. Most recently, though, Mavic has turned its engineering talent to apparel and protection, giving us the peloton-ready, Plasma SLR Helmet.

In fact, this well-made helmet has every promise of becoming as ubiquitous as the Mavic wheels themselves. First and foremost, Mavic have taken a hard look at how it can create helmets with a supreme fit, a light weight, and strong ventilation, while remaining extremely safe at the same time. 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.

And knowing that the best of us get caught out after dark, 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.

If the Helmet fits...

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

And fit (and maybe looks) are pretty much what it's all about with a helmet. Well, of course it's nice to have it be light, with a good number of air vents for cooling. But for me and my small knobby head, it all comes down to fit. This is a beautiful helmet, it just looks fast sitting on the shelf. Unfortunately, I found it too tight in the sides, and worst of all the foam hit the back of my head in just the wrong spot. The Louis Garneau that I also bought (see it in my reviews) just worked out to be a better fit. Lesson learned, buy a bunch of different helmets and try them on to see which fits your head best.

  • Familiarity: I've put it through the wringer

Used last season for 1700 miles. Light, comfortable, absorbs sweat well, and still looks out of box new.
First Mavic product used. Sold on quality of Mavic.

perfect for half the price!!!

  • Familiarity: I've put it through the wringer

I finally decided to upgrade my helmet a while back. Why not go all out on a $200+ helmet for half the price, right? The Mavic Plasma SLR matte black not only looks bad ass, but it feels bad ass. I'm not a weight weenie, but the lightness, air flow and aerodynamic shape is just awesome.

The only complaint I'd say is the strap length. It's uncomfortable around my ears and I always have to adjust it before each ride so it's a bit of a hassle. I also wish there was a thin padding around the chin. That would have been a plus

Perfect Helmet for Me

  • Gender: Male
  • Familiarity: I've put it through the wringer

I recently decided to replace my tried and true well used Giro Atmos helmets with a new ones. For me the Giro was the perfect balance of ventilation, weight and fit. I looked at all the new offerings and decided to try out the Mavic Plasma SLR as one of my options. And I am so glad I did. While a bit heaver then the Giro Atmos or Aeon I do not notice and the fit and air flow make it not matter. And the price here on CC makes it a done deal. I bought two of the SLR's and another non-SLR Plasma for off road. Very pleased!

Great Helmet

  • Gender: Male
  • Familiarity: I've used it several times

I ordered the Mavic Plasma SLR and it fits perfect and looks great. It is solid and very safe. Some have talked about the weight but for a person that rides for fitness not racing it is just fine. It is not heavy at all. So maybe heavier than some of the lightweight racing helmets, but that does not make it heavy. A great helmet for a casual, commuter or fitness rider. Again, fits and looks great. High quality.

Saved my noggin

  • Gender: Male
  • Familiarity: I've put it through the wringer

I ordered this helmet after trashing a Giro Prolite in a crit crash earlier this year. I initially was miffed at the weight, but it didn't end up bothering me. The helmet performed fine through the season until "the incident"... During a large road race, my front wheel was taken out by another rider at 29 mph. I went over the handlebars and down on my head, skidded for a while, then was run over by the pack. Destroyed my frame, shifters, jersey, bibs, gloves, and helmet. I walked away with just road rash.

I attribute the protection of my head to the beefier design and tough shell of the this helmet. It held everything together even though all the internal foam was cracked through. While I am sure that other lighter helmets provide great protection, I'm picking up another Mavic SLR because I know it works great.

After all that praise, I do have to ding it on one point. You can only store your glasses in the front of the helmet due to the vent design.

good helmet alternative

  • Familiarity: I returned this product before using it

I ordered Giro Aeon and Mavic Plasma SLR. 222g vs 295g... price very close to each other but I decided that I like the fit of Aeon better for me and it is significantly lighter.
