Helmets are so varied in design and cost, so how do we know what helmets are good and what are not? A lot goes into that assessment but I hope I can shed some light on the topic.
Why Wear a Helmet?
Helmets are easy to use items that can save your life in a crash (seatbelts are more important though!) so you might as well get one for spirited driving. It does not take much force (ie, acceleration) to damage your brain. We perceive the world through that wonderous organ, so damaging it will affect how we live in most every way. It could affect your life so much as to end it! So keeping your head safe is a good idea. Side note: I wear helmets in pretty much every sport I do…lacrosse, snowboarding, auto racing, cycling to name a few. I’ve worn helmets often enough that I feel naked without them when doing those activities.
How Should It Fit?
Helmets should be snug, especially at first as they will only get looser. The helmet should not rotate/move freely on your head. However, it should not squeeze you so tight that it will cause pain and eventually headaches (I’ve had that happen before I knew better!).
For an autoracing helmet moving the helmet should move your head if you’re not resisting the movement. So if you leave it in a certain position on your head it should stay there. Other sports have other requirements for helmets, for example Lacrosse helmets are strapped to your head quite snugly as they are expected to be struck…often.
Ratings?
There are various certifications for helmets, the most famous of which are the ratings produced by Snell. Snell is a not for profit organization that tests all sorts of helmets. If you’re curious about how they test helmets YouTube does not fail in that regard! There can be various ratings so check your sanctioning body for acceptable ratings.
But why does it matter? For a few reasons: 1) you will never be allowed to race in any respectable sanctioning body without a certified helmet and 2) the certification guarantees a certain level of protection.
Weight?
Weight, believe it or not, affects the safety of the helmet. Weight added to your head means more momentum above your neck. That means a larger force applied to your neck in the event of a crash (this is also why the HANS device was invented). So a really massive helmet will injure you in a crash where no helmet would not.
Fatigue matters, especially in Rally! Extra weight that your neck has to carry will speed up how fast you fatigue. So the lightest helmet possible, with the same protection level, is preferred. However in order to keep it as safe at the same weight, special materials need to be used. Unfortunately for all of us this drives the cost up, but I think it is something worth spending money on.
Full Face vs Open Face
Rally is a motorsport which commonly uses open face helmets, while most of the other motorsports use full face helmets. If you’re curious to the difference visually, here is me wearing a full face helmet and mark wearing an open face helmet (facebook links do NOT require login). There are pros and cons to each of them:
Full face helmets provide a lot more protection to your face (teeth and nose) but come with the downside of trapping more heat and adding weight. While open face helmets provide less protection to the front of your head but cut down on weight and heat. But there is one unique thing in Rally that makes open face helmets dominant: Co-Drivers.
Rarely will a Rally co-driver wear a full face helmet. Why? Because they need to scream at the driver and a piece infront of the mouth muffles the critical sounds that much more. So it almost makes more sense for the driver to be wearing a full face (Sebastian Loeb) while the co-driver dons the open face.
Do you have a favorite helmet brand/style/color?
