While part of the thrill of racing downhill is the blast of wind in your face, as trails have become more gnarly and bikes have become more sleek and quick, it’s important to think about how to protect your head and face. Indeed, mountain biking has come a long way from the days of repack races and klunking down old fire roads.

This evolution in riding styles has ushered in a revolution in safety gear, particularly in helmets. After all, your noggin is the most important thing to protect if you have an unexpected OTB (off the bike) experience. This is why riders today make the effort to shop around for the best full face mountain bike helmet on the market.

A particular favorite with downhill, lift assist, and free ride bikers, a full face helmet offers advanced protection for rides where the risks of a spill are more serious. Not only are falls more common off-road, but the consequences are often more severe.

Road rash pales in comparison to whacking your head on a boulder. In spite of this, there is still a debate among some riders about whether to wear a half shell or full face helmet. For others, the answer is clear: full face all the way.

Both half shell and full face helmets protect your skull, but a full face helmet encases your whole head. This offers protection for your ears as you crash through branches, and for your nose, teeth and jaw bone as you crash through rocks and logs. Nobody sets out to go down, but it happens to even the most cautious riders. Finally, many riders are choosing to wear neck braces, and those should only be worn with a full face helmet.

The Basics

First, get to know your way around a basic helmet. Most helmets consist of three parts, the liner, the shell, and the straps.

  • The liner is the most critical part of the system. It is usually made from molded polystyrene foam. This foam is shot into a mold, where it expands to create the basic structure of the helmet. On top of this, some manufacturers use nylon or even metal mesh as reinforcement, especially around vents. The main purpose of the liner is to absorb the impact in the event of a crash and to redistribute it more evenly around the impact area. Not only does this protect the physical structures of your skull, it also reduces the net g-force experienced by your brain.
  • An outer shell covers the internal liner. Sometimes this outer shell is made from the same material as the lining, while in others it may be made from lightweight, durable materials such as fiberglass. In some helmets, the outer shell is simply glued to the outside of the lining. In other helmets, the lining foam is expanded into the shell, bonding them together.
  • Finally, the straps are meant to allow you to adjust the fit and keep the helmet securely in place. The straps are typically made from nylon or polypropylene, and are attached through a series of cinches, joints and wheels that let you dial in the perfect fit. A properly adjusted helmet feels more comfortable and offers better protection.

No matter the style of helmet or the materials it contains, in order to legally be as a mountain biking helmet in the United States, the helmet must meet the standards identified by the Consumer Product Safety Commission. Look for the CPSC label on any helmet you are considering.

Note that these are different and far less rigorous requirements than the Department of Transportation (DOT) rating given for motorcycle helmets. It should also be noted that there are ratings that go above and beyond the one offered by CPSC and are used to rate the helmet’s safety for various types of biking. If you plan to be involved in competition, find the minimum rating requirements for your sport’s governing body.

Considerations

What kinds of things should you consider when picking out the perfect helmet? Some key considerations should be comfort, fit/protection, weight, and the presence of a visor.

Comfort

Let’s face it, if your helmet isn’t comfortable, you aren’t likely to wear it. At the very least, it will seriously detract from your enjoyment of the ride. One of the main comfort features is moisture-wicking padding that protects your head from direct contact with the helmet lining. Look for a helmet that, when properly fitted, doesn’t place pressure on any one spot on your head.

Fit/Protection

Speaking of a proper fit, a quality adjustment system in the helmet is a must. This is called the retention system, and is typically made of a series of firm plastic, straps, cinches and dials that let you orchestrate the perfect fit.

First, you’ll dial in the firm plastic around the lump on the back of your head (the occipital bone), then snug everything else into place. If your helmet slides around too much, it won’t be there to protect you when you need it most.

Weight

Many riders consider weight to be a big factor when choosing a helmet, however, with the lightweight materials on the market today, you won’t find many that weight too much. The differences will most likely be subtle, and sometimes the right fit can make a helmet feel much lighter than it actually is.

Visors

Visors come in varying length and widths to block out glare from the sun. Some helmets come equipped with fixed visors, while others have fully adjustable visors so you can get the angle and coverage just right. Higher end helmets feature break away bolts on the visor attachments to prevent the visor from snagging and twisting your neck during a fall.

    I know a lot of off road bikers who are reluctant to consider a full face helmet, either because the don’t like the look or the feel when they’ve tried them on in store. In my experience though, wearing a full face helmet makes for a more confident, and ultimately more fun ride. Is there a period of getting used to it? Sure, but that like all other things will fade, and the fact is that you are likely to be much safer.

  • Mark Foster

    It’s important that when you buy a mountain bike helmet, look for the Consumer Product Safety Commission (CPSC) label to ensure that it meets safety standard. There will always be pros and cons of of wearing a full helmet vs half shell. But it’s really foolhardy to wear nothing when you’re active on this sport. The risks of injury for downhill biking can’t be overlooked. No brainer. 🙂

  • Tonya Murphy

    I watched a horrible accident when a person feel off their mountain bike without a full coverage helmet and a small twig had impaled their cheek. This is so important! I understand not wanting to-they feel bulky and can get sweaty- but head gear can be life saving and certainly shouldn’t be skipped.

  • Phyllis Perez

    Protection is so important. I hate seeing people riding around without helmets. And then when you’re doing something like mountain biking a full face helmet is something I would consider essential. Of course it’s awkward but I’d rather be awkward than unsafe. Some of these are cool, though. I like the Triple 8 Invader!

  • Mark Foster

    Hi Phyllis! Riding without helmets are just too risky. Whether you’re riding off-track, or in the city helmets give you the protection you need.
    These babies were made for a reason and the materials used for these are the latest in technology. Today, you’ll find lightweight helmets that offer full protection for your face. Falls from bikes are very common. And when you’re thrown-off, these helmets will cushion the impact if your head hits the ground.

  • Mark Foster

    That’s just it – you can’t discount a fall. Remember that these are extreme sports and if you do indulge in these, you’d better be protected.
    Investing in a quality helmet is essential. I advise riders: do not scrimp on these important headgear. You’ve got to find a brand that is trustworthy and is the top choice of biking enthusiasts. A perfect fit is important in order to get the most benefit.
