Klim F5 Helmet Review


There is no doubt about how vital ventilation is when we choose apt protective equipment for ourselves, and this is where the F5 helmet stands out.

Klim has specifically engineered this gear with four big chimney vents on the top of the helmet that allows the pent-up heat inside to escape in the air from the top directly.

This feature is especially useful when there isn’t a steady flow of air around the snowmobiler (this happens when you are riding at slow speed or side-hilling or when you are riding across deserts or hot climate terrains where there is the restricted flow of air), thus eliminating the need for high-speed for proper airflow.

The tube-like design of the helmet enables the liberal flow of air with minimal hindrance.

Fit and Comfort

The fit of any helmet eventually depends on the individual himself, as it defers according to the shape and size of the head.

Therefore, it is essential to try out any helmet before buying because the product could be great, but it renders useless if it doesn’t fit you correctly.

That being said, the Klim F5 helmet has an aesthetic and a supportive fit and is available in different sizes for meeting the needs of different wearers.

The inside is well shielded to keep your face warm and comfortable.

The drawn-out chin strap in the helmet is snug and securely held.

It also has cushy cheek pads inside, which are held in place by detachable snaps.

Overall, it is a close-fitting helmet but at the same time, it is not too tight to suffocate the rider.

With smooth airflow and well-structured design, comfort with Klim F5 is inevitable.


We can’t talk about comfort without discussing the weight of the helmet now, can we?

Every other feature of the helmet becomes pointless if it is too heavy on your head.

However, the first thing you will notice when you pick up the Klim F5 helmet is how light it is!

You can immediately tell how much thought has been put into making sure that the helmet is airy and weightless.

The helmet is encased in a carbon fiber shell with three density EPS (expanded polystyrene)

Klim uses three different densities of EPS to make sure that it provides maximum protection with minimum weight.


To begin with, Klim F5 is ECE and DOT certified, which is as safe as any helmet gets.

Klim helmet comes with Koroyd technology, which provides more energy absorption and enhances safety with innovative energy management components.

Besides this, the F5 helmet also provides MIPS (Multi-directional Impact Protection System), which is a state-of-the-art technology that is another major USP of Klim.

MIPS is a brain protection system that is placed in the helmet to reduce collision impact and provide protection against the rotational movement to the brain from angled impacts to the head.

Between MIPS technology and the Koroyd layer, the Klim F5 claims to provide a substantial reduction in HIC (Head Injury Criterion).

Klim has clearly put in significant efforts and invested in the latest technology to make safer helmets for their riders.

Klim F5 Helmet vs. 509 Altitude

The Klim F5 is one of the most advanced helmets in the industry. Its use of exclusive premium materials, innovative technology, and precise fit make it the perfect solution for snowmobile riders who are looking for both comfort and performance.

One of the things that you will notice instantly about this helmet is how light it feels.

With its lightweight yet high-quality construction, the Klim F5 helmet is the perfect choice for the most demanding snowmobilers looking for a high-speed snowmobile experience.

In addition, Klim takes pride in the F5 helmet to be the most ventilated helmet in the industry. This next-gen helmet sets the new standard for ventilation offering unmatched comfort on the trail.

On the other hand, the 509 Altitude helmet focuses more on providing maximum stability, coverage, and protection against impact.

When it comes to the level of protection it offers, this helmet has everything you need to be prepared for any snowmobile riding condition. Its versatility and security give it an edge over other helmets in the market today.

With the Altitude’s design, you get precision fit and aesthetics, critical to your visibility as well as comfort and airflow to keep you snowmobiling at your best all day.

Final Words

comfortable helmet for snowmobile riding

Like I mentioned above, 2021 is not the year to take chances. Although many things are beyond our control, choosing the right helmet is something that is still in your hands.

Undoubtedly a generic helmet needs to provide adequate safety and comfort with strong durability; however, the additional properties offered by the company are what make that helmet stand apart.

And I believe Klim F5 is truly a great option to consider if you are a snowmobiler looking for a helmet that provides you with state-of-the-art features and superior technology for a premium experience.
