Technologies
MIPS®
CAIRN And MIPS® have together developed a helmet that is even safer for your head. Thanks to the system MIPS® (Multi-directional Impact Protection System), the rotational forces generated during an impact are absorbed, reducing the risk of brain damage and guaranteeing enhanced safety on the slopes.
FIDLOCK®
Because the ergonomics and safety of a helmet are important, helmets equipped with a magnetic buckle FIDLOCK® allow you to open and close the helmet with a simple gesture.
AERO FLOW
The Aero Flow system is a technology that promotes air circulation in the helmet. Consisting of channels carved into the EPS, it naturally ventilates the helmet, carrying air from front to back for a constantly regulated temperature.
ANTI-INSECTS
Designed for your comfort and safety, our bicycle helmets feature an anti-insect net cleverly positioned on the front vents. This net offers optimal protection against flies, mosquitoes and other flying insects, without compromising the ventilation of the helmet.
FLASH LIGHT SECURITY
Helmets equipped with the system Flash Light Security have a rear lamp with 3 lighting modes, ensuring optimal visibility to be seen by all.
REFLECTIVE
Urban, children's and junior helmets equipped with the Reflective System incorporate judiciously placed reflective strips, offering better visibility on the road and enhanced safety.
OCCIPITAL PROTECT ZONE
For more committed practices but also for the safety of your children, CAIRN set up theOccipital Protect Zone. Its aim is to maximize the safety and protection of your head through a more covering shape on the back of the skull, allowing it to be better protected and more secure in the event of an impact.
REMOVABLE LINING
All of our helmets feature detachable, antimicrobial and washable liners. CAIRN has selected the best foams to improve comfort and indirectly contribute to everyone’s safety.
IN-MOLD
Helmets In-Mold are the lightest on the market. The internal EPS is directly injected into the polycarbonate shell, thermoformed beforehand. The 2 layers are inseparable and allow the shock to be distributed over the entire surface for optimal absorption and protection.
ABS
The helmets in ABS offer better resistance to shocks and impacts. Made up of an internal EPS shell covered with a thick shell in ABS thermoformed, they are resistant and durable over time.
MTB bicycle helmets
The mountain bike helmets Cairn offer enhanced protection and optimized ventilation to tackle technical trails and challenging terrains. Lightweight and sturdy, they ensure comfort and safety for mountain bikers, whether they ride cross-country, enduro, or downhill.
