Instead, this helmet made use of the 360 Turbine Technology that helps in dispersing the rotational forces using the tiny turbine-like circles that were made of Armourgel. These tiny circles were placed in different ideal spots of the helmet. These are soft materials that harden up once there’s impact.

How to buy good mountain bikes helmets

What makes the best MTB helmet? Does it have to be a full-face helmet or a half shell design will already get the job done? Do you buy an entry-level helmet where the plastic shell and the EPS are glued together? Or are you willing to go for the more expensive options instead of molded as one piece?

Meeting Standards

Helmets should meet certain standards. In the US, you have the Consumer Product Safety Commission (CPSC) that is in charge of regulating the MTB helmet industry. You have the CPSC that gives its seal of approval to helmets after tested in the laboratory.

Other certifying organizations used other baselines for their seal of approval. However, you have to note that 400 G-Force can cause permanent brain damage, while 300 Gs will most likely give you a concussion. The goal of certifying organizations such as Snell, ASTM, CE, and CPSC is to make sure that users don’t get permanently injured.

The best mountain biking helmets don’t just meet the bare minimum requirements of these organizations. Rather, the safest mountain bike helmet should surpass the standards and offer minimal damage to your head in case you encounter an accident.

However, the downside is that mountain biking accidents can be tricky. In most cases, you just can’t quantify the severity of an accident and mimic everything based on numbers that you get from a lab.

Construction

When it comes to choosing from the different MTB helmet brands that produce top-rated MTB helmets, you want to check the foam liner found between your head and the outer shell of the helmet. This is usually made of expanded polystyrene or EPS.

The role of EPS on best helmets for mountain biking is to spread the energy once there’s impact. Upon impact, the foam is going to be deformed. This slows down the energy making it possible to lessen the damage on its user. The EPS density can be different depending on the application. It is softer for slow speed impacts and harder for high-speed impacts. However, these days, there are top mountain bike helmets that utilize both to give you the best of both worlds.

The outer shell is equally important when it comes to selecting your mountain bike helmet. The outer layer protects the EPS plus its smooth surface is helps in your aerodynamics. If you are going to look at the cheap MTB helmets, you will notice that the EPS is glued to the outer shell. However, for the more expensive version, you have the shell bonded with the liner during the molding process.

The in-molding option is better in terms of performance because these mountain bike helmets provide better protection to the EPS liner. It is also easier to spot dents and cracks which means that it is easier to know if your helmet isn’t offering optimum protection to your head anymore.

Designs

Do I go for full-face or do I go with half face helmets? The likes of an enduro full-face helmet such as the giro full-face helmets are now popular offering greater coverage of protection to its users. However, you also have the open-shell design that is known for being lightweight.

Of course, different people have different needs. The design of your MTB trail helmet will depend on your lifestyle. Are you a serious rider or are you a casual rider? If you’re a casual rider, it’s better if you go for the lightest MTB helmet which is most likely a half-face or half-shell MTB helmet rather than an enduro MTB helmet.

Now, if you plan on doing rugged terrains and doing full speed biking, then you might want to find the best full face MTB helmet instead of the low profile mountain bike helmets.

MIPS technology

There’s a growing demand for a MIPS MTB helmet. And it is for good reasons. MIPS stands for multi-directional impact protection system. The ultimate goal of this technology is to reduce the rotational forces when you get into an accident. It uses a slip-plane system that moves within the helmet. This rotates within the helmet to slow down the energy that transfers to your head.

With a technology that was developed by brain surgeons, a MIPS mountain bike helmet looks different on the inside. You will notice that there is a thin liner underneath.

Fit

Another important factor that you need to consider when shopping for the best MTB helmets is the fit. Wear something that is too loose and you might not have the helmet upon impact. On the other hand, wear it too tight and you also don’t get the comfort that you need while riding.

What’s the general rule of thumb for a mountain bike helmet’s fit? The best-rated mountain bike helmets are usually adjustable but you need to make sure that the helmet remains in contact with your head at all times. There should also be no obstruction in your view. And also, if you have straps on your trail helmet, it shouldn’t let the helmet to move more than 1 inch from that level.

If you’re using an enduro bike helmet, the foam by the side shouldn’t feel too snug. But in most scenarios, it is going to fit according to your head.

Ventilation

One of the usual complaints of riders is that their all-mountain bike helmet tends to get hot especially when you use it for long hours. Regardless if you are going to buy a budget MTB helmet or something more expensive, you want something that is also comfortable. Some of the most comfortable mountain bike helmet options have vents to get the air to go in and out.

However, it is always important to find a balance between comfort and safety. Having more vents means that you are compromising the ability of the helmet to nullify g-force.

Accessories

Over the years, riders use different accessories when they ride their mountain bike. For instance, a lot of riders now install a GoPro on top of their helmet. Some mountain biking helmets are mount ready while others will require a few modifications. Some downhill trail helmets also offer compatibility with goggles. This way, you are protected from dirty that might hurt your eyes and distract you from the road.

And lastly, you have the helmets that have vents where you can place the lights. This way, you remain visible if you are going to be riding at night.

Conclusion

Riding your mountain bike can be dangerous without the necessary protective equipment. Helmets improved over the years to promote safety reducing not only injuries but even fatalities. There are a lot of great mountain bike helmets to choose from. But if you are looking for the best mountain bike helmet, you want to consider comfort, coverage, and the technology used by the brand. Also, you want to make sure that you are going to compare different helmets before you even buy one. This way, you will know the pros and cons and weigh in properly which option works best for you.
