Kask Protone

Cycling is becoming an increasingly popular physical activity mainly because it is affordable and has many health benefits. However, as everyone is exposed to the risk of injury on the roads regularly, cycling is not free of danger as well.

Though cyclists suffer a wide range of injuries as a result of collisions, head injuries have been identified as a leading cause of death and serious injury in cycling accidents. Wearing a cycling helmet is one way for cyclists to avoid or minimize the severity of a head injury in an accident.

When it comes to road cycling, a good quality helmet should be lightweight, aerodynamic, and improves shielding to protect you in the event of a collision. In hot weather and during strenuous efforts, ventilation is also important for temperature regulation.

Therefore, Kask has created an ultimate aero road helmet in partnership with Team Sky, the UK’s premier cycling team. They create Kask Protone Helmets with exceptional heat dissipation properties and incredibly low drag coefficients for completely vented helmets by using Jacquard wind Tunnel CFD expertise.

The Protone is handcrafted in Italy and is the fourth helmet designed in collaboration with Team Sky following the Kask Mojito, Bambino, and Infinity. All of KASK’s innovative design features and higher-quality materials used in this helmet are fully licensed, patent-protected, and exclusive to KASK.

Along with its luxurious feel and sleeker finish, the Kask Protone will provide unbeatable comfort even under the most demanding conditions.

Kask Protone Helmet Features Review

Let’s take a closer look at the revolutionary features of Kask’s highly successful Protone helmet, worn by some of the world’s finest riders.

Shell Construction & Design

Kask Protone helmet is constructed with an outer polycarbonate shell that is connected with an inner polystyrene cap by using Kask’s innovative in-molding technology.

Protone, according to Kask, was designed with computational fluid dynamics software to have the lowest drag coefficients of any ventilated helmet.

It is internally equipped with a reinforced composite skeleton that provides improved mechanical strength and compactness while also prevents the helmet from shattering into several pieces in a crash.

Further, this In-molding technology protects the less durable parts of the EPS shell, which are typically left uncovered by helmet manufacturers to minimize the weight and expense of the helmet, hence increasing the durability of the helmet.

The wind tunnel-tested shell of the Protone helmet is well-ventilated and offers a low-profile and aerodynamic design. Also, this helmet is quieter and offers good wind noise control.

Safety Technology

The main purpose of a bicycle helmet is to reduce the extent of injury to a cyclist’s head during a collision.

Kask is committed to putting safety first, by using its Multi In-molding Technology (MIT) which creates a polycarbonate cover for the top, base ring, and back of the helmet’s shell.

This MIT technology of Kask Protone works great to reduce the impact energy absorption by the helmet.

The high visibility sticker on the back allows for maximum safety even in poor visibility conditions.

Kask’s WG11-certified helmets set a new standard for protection against rotational damage. It’s a European standard for determining a helmet’s ability to absorb energy during linear and rotational impacts. It’s a much tougher test to pass and ensures greater protection as compared to the MIPS liner.

Kask Octo Fit Retention System

The Octo Fit adjustment system from Kask guarantees a perfect fit for any head shape or size. The initial fit is done with the bar that slides up and down into the helmet to set the vertical position of the cradle on the head and allow much more vertical adjustment than most helmets provide. The main fit is completed in the back with the use of a ratchet wheel to strengthen the entire system.

The helmet’s fastener has tiny clicks that allow for micro-adjustments, and the self-adjusting lateral divider provides pinpoint accuracy with minimal adjustments.

For riders whose helmets often collapse forward and back on their heads, this retention device is perfect.

Chin Strap

The chin strap construction of Protone is different from what you see on other helmets. It is designed to sit flat against your skin to provide a comfortable fit. There are no dividers underneath your ears.

Protone’s Eco-leather synthetic chin straps are anti-allergy to help prevent skin irritation. They can also be washed separately from the helmet to maintain hygiene.

Ventilation

Kask speeds up the game by making this Protone helmet extremely comfortable with more aerodynamic properties as compared to the other standard road helmets.

Protone helmets have strategically mounted 20 vents with an internal channel system to maximize the airflow through your entire head. The ventilation system works by taking in cool air from 7 large front vents which operate in tandem with the rear vents to provide hot air escape. The air that enters through the front vents cools your head before exiting through the back vents, which expels the hot air that has accumulated.

The Kask Protone’s ventilation lagged only when ascending at slow speeds in hot weather.

For better aerodynamics, there is a small area near the back at the top of the helmet that is devoid of vents.

Comfort & Fit

The Kask Protone helmet features 3D-dry technology and Coolmax interior padding, making it extremely comfortable to wear even for long rides. Its multi-layer open cell construction has circular perforations that reduce the surface area and provides the fastest sweat-wicking for a comfortable trip.

Kask Protone helmets have silicone softeners all around the edges that add to the comfort when you tighten the helmet onto your head. Also, the leather chin strap feels comfortable on the skin.

The helmet’s overall depth ensures a complete snug fit without causing any discomfort, guaranteeing excellent ventilation and freedom of movement

Weight

The semi-aero Protone helmet weighs just 230 grams. This lightweight helmet helps you to move your head more freely, which allows you to be more aware of what is going on around you so you can spot possible hazards more quickly.

Even though Kask Protone has a thicker polycarbonate shell over the EPS foam to protect the helmet from small bumps or drops, which adds to the weight, its aerodynamic properties make it better than other road racing helmets.
