Highlights & Technologies:

AIREVAC:
Ventilation holes in the front section of the helmet allow for a constant air flow. Thus, cool air can enter the ventilation system while warm air can escape through the rear vents. The constant airflow provides especially high comfort and optimal temperature regulation.

INMOULD:
The liner is fused with the outer shell under high pressure and strong heat for a lasting connection. This makes the helmet very robust and lightweight.

KOROYD:
Thousands of small and very light polymer tubes form the Koroyd core that offers especially high impact resistance. Besides, the energy-absorbing material is very breathable, which ensures perfect thermoregulation and keeps your head cool while cycling. Integrated ventilation channels support the ventilation concept.

WHAT IS MIPS?
MIPS (Multi-Directional Impact Protection System) is a slip-plane system within the helmet. It is designed to rotate inside the helmet and thus slow down or reduce the impact energy acting on the brain, which helps reduce head injuries caused by rotational impacts.
WHY IS MIPS IMPORTANT?
When a head rotates quickly and comes to a sudden stop, the rotational acceleration may cause the brain tissue to experience high levels of strain. This stretching of the tissue caused by these motions may result in various types of brain injury. MIPS is designed with the intent to address rotational acceleration from impact.
HOW DOES IT WORK?
MIPS uses a slip-plane system that moves inside the helmet, mimicking the brain’s own protection system. This layer is designed to rotate inside the helmet with the intent to potentially slow or reduce the amount of energy transferred to or from the head. Science tells us that if we can reduce the strains associated with rotational acceleration, we might reduce the risk and severity of brain injury.
