Kask Protone Helmet: Why Cyclists Are Raving About It

The question remains. Is the Kask Protone Helmet the ultimate choice for cyclists? Let’s find that out.

An All-Round Winner

An All-Round Winner

From design to performance testing, Kask takes pride in producing all its helmets in Italy, and the Protone is no exception.

This commitment to quality shines through in every aspect of the helmet’s design and functionality.

Smooth and Ventilated

Smooth and Ventilated

The Protone boasts a semi-aero design, featuring large forward-facing vents coupled with a smooth top that minimizes turbulence.

Tested in the wind tunnel, this helmet showcases an impressive coefficiency rate regardless of its position on your head.

It’s a winning combination of speed and ventilation that caters to the needs of road racing enthusiasts and high-intensity trainers alike.

Strength and Protection

Strength and Protection

While the Protone excels in many areas, one notable omission is rotational protection. When the helmet was originally designed, the MIPS technology was still new, and Kask chose not to adopt it.

Instead, they rely on an inner frame to produce a slimline helmet without compromising safety. The strengthening frame increases structural integrity, holding the helmet together in the event of a crash.

In-moulding further safeguards the polystyrene, protecting it with a layer of polycarbonate.

Comfort at Its Core

Comfort at Its Core

Kask understands that comfort is paramount during long rides. The Protone features an inside lining with multilayer padding made from Coolmax material.

Not only does this padding ensure a snug fit, but it is also treated with an antibacterial and antimicrobial sanitized process, keeping the helmet fresh and odor-free.

In a departure from standard webbing chin straps, Kask opts for a synthetic eco-leather material. This choice enhances both the tactile experience and the functionality of the strap.

The stiffer material ensures that the strap holds its adjustment, minimizing any distracting flapping while you ride.

A Perfect Fit

A Perfect Fit

The Protone’s Octo Fit head retention system takes adjustability to the next level. Both vertically and horizontally adjustable, this system allows for greater control over the helmet’s contact points.

Additionally, the retention system accommodates those with ponytails, catering to diverse hairstyles and preferences.

When you wear the Protone, you’ll experience a snug encapsulating fit across your entire head, providing a sense of being locked into the helmet rather than simply wearing it. The retention system enhances this feeling by scooping low around the back of your head.

Adjusting the system to your preferred tightness is a breeze, simply click down and wind.

Excellent Ventilation

Excellent Ventilation

Ventilation is crucial during intense rides, and the Protone delivers. The central vents feed cooling fresh air through channels across the top of your head, effectively dissipating heat buildup.

 Even at slower speeds, the airflow remains noticeable, quickly refreshing you after demanding efforts.

However, in hotter climates, the Protone may reveal slight ventilation weaknesses, but fear not, as Kask offers the Valegro helmet for those who relish sweat-inducing climbs.

A Balanced Combination

A Balanced Combination

Weighing in at a competitive 268 grams (size Medium), the Protone strikes a good balance between lightweight construction and robust durability.

While other helmets in the same weight class may include a MIPS liner, the Protone’s durable build compensates for this omission.

Considering its semi-aero nature, the weight of the Protone is more than reasonable.

Q: Can the Kask Protone Helmet accommodate additional accessories, such as lights or cameras?

A: Yes, the Kask Protone Helmet is designed to be compatible with various cycling accessories. It often features integrated mounts or clips specifically designed for attaching lights, action cameras, or other accessories.

Q: How does the Kask Protone Helmet contribute to rider safety?

A: The Kask Protone Helmet meets stringent safety standards and undergoes rigorous testing to ensure superior protection. Its multi-layered construction, including a durable outer shell and energy-absorbing materials, helps to dissipate impact forces and reduce the risk of head injuries.

So, what’s the truth?

In the crowded realm of road racing helmets, the Kask Protone stands tall with its Italian craftsmanship, semi-aero design, and impeccable ventilation.

While it lacks rotational protection, its inner frame and in-molding construction provide peace of mind. The Octo Fit system ensures a snug fit, while the padding and synthetic eco-leather chin strap enhance comfort.
