Full Face Mountain Bike Helmet Buying Guide

Mountain biker on rocky terrain

We all know that bike helmets are meant to protect your head in case of an impact. In fact, many places require wearing helmets in order for you to ride. These helmets must meet certain standards, but aside from that, how do you go about choosing the right helmet for you? After all, no two helmets are made the same. Some are simply better than others.

Well, there are few things you need to consider, and we’ll talk about each of them below:

What are MTB helmets?

First things first. What are MTB helmets, exactly? How do they differ from other types of helmets? To give you an idea, MTB helmets are different from road lids and high-end racing helmets in more ways than one.

These days, mountain bike helmets come in significantly more lightweight profiles while offering considerably more protection with full coverage that protects your entire face, head, and even your neck. This is important with the increasing popularity of certain riding styles such as enduro racing, trail center riding, and all-mountain riding, which all emphasize the downhill experience.

Some mountain biking helmets come with visors, although it’s more common in road racing helmets. This is helpful in protecting you against the glare as well as the outdoor elements. Most helmets, however, have bug meshes on the front vents to keep insects at bay, so these are two things you know you should look for.

Types of bike helmets

Aside from mountain bike helmets, which typically come with extended coverage at the rear as well as plenty of intake and exhaust vents, there are actually two other types of bike helmets. These are road bike helmets, which are lightweight and aerodynamic, and recreational bike helmets, which are an economical choice if you want to partake in casual riding.

What’s important here is you choose the right type of helmet depending on your style of riding so you can enjoy the right level of protection.

Fit and fit adjustment

Now, the first and most important thing you need to make sure of is whether the helmet even fits you properly, since a poor fit can severely compromise your protection in the event of a crash. Besides, an ill-fitting lid will be uncomfortable to wear after a certain period of time.

Here’s a guide on how you can find the right size of a bike helmet, which you can determine by measuring your head circumference with a simple tape measure.

  • Extra small- 20in/ 51cm
  • Small- 20-21.75in/ 51-55cm
  • Medium- 21.75-23.25in/ 55-59cm
  • Large- 23.25-24.75in/ 59-63cm
  • Extra large- above 24.75in/ 63cm

Regardless of what size you opt for, make sure that the helmet can provide a more customized fit with the use of easy to adjust retention systems so you can manipulate the helmet’s circumference and tilt. Ideally, these adjusters should be made with solid and durable materials rather than cheap plastic.


The helmet should also have lots of internal cushioning to make the helmet’s fit more stable and comfortable. Depending on the material, this padding can even help with heat management by absorbing sweat and allowing for added breathability. The best paddings, therefore, are ones that are removable, washable, and come with moisture-wicking properties. 

The general rule here is if you ride in a warmer climate, choose padding that’s thinner and more forgiving so it’s more comfortable against your head. On the contrary, thicker pads will offer more comfort and warmth in colder climates.


One common feature of MTB helmets is MTB peaks, which are excellent in keeping sunlight, crud, and mud out of your eyes. That said, there are a few important things you need to remember. One, the peak should be stable, adjustable for tilt, and rattle-free.

Two, if it comes with a visor, this should be made with breakaway fixtures and flexible materials to make sure that it’s safe to ride with, and won’t cause neck injury in case you get into an accident.


A helmet is a pretty enclosed gear, which is great for protection, but bad for breathing, considering that you’re wearing it over your face. As such, it’s a must that the helmet has lots of ports and vents to facilitate airflow and keep your head cool rather than dripping with sweat. Try to find a helmet with plenty of well-placed vents, which should be covered with a bug mesh.

Chin Strap

When it comes to chin straps, you should put equal stress on comfort and safety. Meaning, the strap should be easily adjustable, and should not be itchy or flappy, nor dig in your face. You generally have the choice between simple plastic clasps that are light and unobtrusive and more complex magnetic clasps that are faster to install.

Safety Features

Did you know that aside from the hard plastic shell and variable foam densities that helmets are made with, there are often other safety features with it to enhance its protective capabilities? These include rotational impact protection in the form of MIPS, which is an independent plastic liner that’s extra slippy and works great in dissipating impact energy.

Other great specialized protection includes WaveCel, which is found on many Bontrager helmets and makes use of a honeycombed lining engineered to offer a crumple zone that absorbs primary and rotational impact forces.

There’s also the SPIN, a technology widely used on POC helmets, which makes use of silicone injected pads contained in a special movable structure within the shell. It works in redirecting rotational impact energy in the event of an impact.

Chinbar attachment

Many helmets come with removable chinguards that let you conveniently switch between uphill mode to downhill mode. These chin bars are made with varying safety standards, with some suitable for basic trail riding, and others with a complete DH certification. They also have unique clamping mechanisms.

What you need to remember here is that the chin bar should fit easily and quickly even with your helmet already in place.

Other features

There are lots of other features that mountain bike helmets these days come with. These range from visors that shield your eyes from the sun, wraparound chin bars that offer full face protection, mount compatibility for installing action cameras, goggle clips and parking, and so much more.

If you really want to get the best value for your money, choose the right sets of features that you feel you will most benefit from, rather than trying to find a helmet that comes with all of the top features imaginable.

Protection standards

Finally, make sure that the helmet you’re eyeing for actually passes minimum safety standards, which include puncture resistance, the capability to handle impacts of varying velocities, strap integrity, and more. The best helmets out there in terms of protection are the DH certified ones, although they are also heavier and bulkier, not to mention more expensive.


Remember, helmets are made with integrated outer shells and inner liners that work together in protecting your head against impact. This works by shielding you from puncture, as well as slowing down and dissipating impact forces. Ideally, they should also be paired with a layer of specialized protection to further shield you against impact forces.

That said, the best full-face mountain bike helmet is one that meets all your personal needs and requirements, and of course, your budget. There are plenty of amazing options out there, and as long as you know what to look for, you are sure to find the right helmet for you.
