Float Fit™
Float Fit optimises the fit of the helmet in 2 ways - in terms of head circumference and vertical adjustment.
In order to reduce weight and simplify operability, the guide arms are uniquely designed to enclose the back of the head thanks to the "float" design. This puts the helmet in an ideal position on the head. Simple, light and comfortable.

GoggleGuide™ Adjustable Visor
The adjustable Goggle Guide visor system holds the goggles securely in place. The visor can be easily slid upwards, providing enough surface area on the helmet to "park" the goggles on. If you are travelling without a visor, the short Goggle Retention Arms are used. They hold the strap securely in place and prevent the glasses from slipping upwards.

In-Mould™ Construction
With the In-Mold construction, the robust polycarbonate outer shell is bonded to the impact-absorbing EPS inner shell in a single operation during the foaming process. This makes the helmet even more resistant - without additional weight. This production process also makes it possible to form much better ventilation systems and openings.

Ionic+™ Padding
The Ionic+ pads have silver threads woven into them, giving them an antibacterial effect and preventing odour build-up. They are quick-drying and cool in the heat and warm in the cold.

MIPS®
MIPS (Multi-Directional Impact Protection System) is a unique technology that protects the brain in the event of an oblique impact. The principle of the natural low-friction layer of the brain is adapted in order to minimise the forces that occur.

No-Twist Tri-Glides™
It is all about the details. The strap system is easy to adjust, keeps the straps flat and prevents them from twisting - which also helps to take a few watts off the wind.

Sweat Guide™
The padding design directs liquid and sweat away from the forehead padding and away from the helmet via goggles or glasses.
