That’s why wearing the best mountain bike helmet possible will be critical for your safety. Along with some knee and elbow pads, you can protect yourself from damage if you get to fall when riding.
But nothing compares to the importance of the helmet. Protecting your head in this situation can even be life-saving.
For that, here we explain all about the best MTB helmets as well as a review of each so you can learn more about all the highest-quality options out there.
If you’re in search for one of these, then you’ll be happy to scroll down and find out more about them!
Is A Mountain Bike Helmet Different From Road Bike Helmet?
The most common type of bike head protection is the road helmet. It is small and rounded, and it doesn’t cover the head completely. In fact, it leaves certain places open for air to pass through and the face totally uncovered. This type of helmet protects really well and provides excellent versatility that road bikers enjoy.
But mountain bike helmets are not too different really. The only significant change you may spot while looking at a road helmet and an MTB one is that the latter comes with a visor. Yes, that’s the main difference because in the mountains you usually find more dirt, sand, mud, vegetation and even sun rays than in roads.
Apart from the additional protection a visor offers, MTB helmets may also come with an extended front or visor. This front may have a cap-like shape that adds an extra layer of protection from falls. In case you fall forward, your face won’t meet the floor directly thanks to the visor.
So you could say both road, and mountain helmets are almost the same. Unless you are looking to enjoy from the extra protection an MTB helmet offers, there won’t really be much of a difference.

What To Look For Before Buying?
Reading some mountain bike helmet reviews is useful so you can eventually pick the ideal option. However, that won’t be enough if you want to choose the best one. For that, here we bring an explanation of all the factors to consider before buying an MTB helmet.
Fit & Comfort
There’s probably nothing that you’ll care the most about a good MTB helmet than the comfort it offers. You will want something that fits perfectly on your head, that leaves no space for fragility, and that eventually makes it easy to ride around without issues. For that, you’ll need to consider several things.
First, make sure the inside of the helmet touches your head ultimately. As long as it doesn’t block your vision and provides excellent comfort, the helmet will be a great choice. Otherwise, if it feels hard or too tight, then you need to pick another option or try to adjust it.
Some options come with a one-size-fits-all design which can be pretty useful so you won’t have to pick among many possibilities. However, it’s always better to go for the right size according to your needs.
We recommend going for those options with at least three different sizes to pick, and additional internal adjustments, so it becomes even more versatile when fitting. And most of them come with the dial adjustment system which makes overall adjustment very straightforward, making them a great choice.
Apart from that, you should make sure the straps are comfortable but also tight enough to prevent the helmet from moving. If the helmet moves an inch or more when riding, it means you’ll need to adjust it or pick another size.
One of them most important things to consider is the type of design. Some options come with a full-face build while others come with an open-face or half-shell. You will have to pick the one that fits your needs accordingly.
We recommend full-face options for users who want more protection on the face and the half-shell for those who want more flexibility & ventilation.
In whatever model you pick, the helmet should stick tightly to your scalp. So when you move the helmet, the scalp moves with it. This will ensure that you have a protective helmet on your head, as long as you place it in the right place.
Materials & Build
You’ll find that most MTB helmets are made of two important materials, EPS and polycarbonate. This happens because of no matter the design, shape, ventilation or adjustability, all helmets need to be protective and light to use.
The first material, EPS, means expanded polystyrene, which is the perfect option for the interior of the helmets. This material tends to be really impact-absorbing which adds to the protective layer of every helmet. However, the great purpose is to feel comfortable in the head. That’s why EPS is mostly known as the liner.
The second material is PC or polycarbonate. This material is hard and works as the shell of every helmet. Its purpose would be to prevent impacts from damaging the interior by absorbing most of the impact force.
This durable material also offers the chance to slide, as it is too smooth in the surface, so you don’t get stuck or snagged while going in mountain trails. And in case you fall or bump into something, then the hard shell will let you know with a crack or dent.
This way you get both the EPS material for the interior that keeps your head comfortable & protected, alongside PC for the outer shell that protects directly from impacts. Other materials for either interior or exterior won’t be as useful as these two.
Ventilation & Aerodynamics
All mountain bike helmets need to come with ventilation holes so air can pass through and deliver a refreshing air to the biker. Most helmets offer several of these holes so the user can enjoy a fresh experience accordingly. However, some offer more vents than others.
The one with more vents can go over 20 holes per shell, this means they can provide a really fresh experience when using. Some may offer only 7, 10 or 12 holes but larger which means they are also breathable enough to feel fresh but not that much.
It is essential to consider that this also changes the overall aerodynamics of the helmet. The products with more air vents tend to be cooling but lack a little speed create. This is not very noticeable when using, but air entering the helmet may slow down or push back the head of the user.
The more holes available, the more air that enters and the more push-back effect you’ll receive. But with the ability to refresh and keep sweat on the line is something you won’t get with all helmets. It’s important to note that full-face helmets rarely come with a ventilation system, so they tend to be hot.
Finally, remember you can find other features in MTB helmets such as chin bars made of plastic for protection. Lens compatibility is perfect so you can add goggles to protect your eyes. Visors are also useful for both eye and front protection.
Then you have lights or rear red reflectors that add visibility at night. An additional option you can find is mounting options for cameras, especially GoPro. These can be pretty useful if you are a vlogger or just want to record your trips.
