Alpine Medium Rage Matte Black/Blue Enduro/Full Face Helmet (0210919116) by Kali®. The Alpine is a super lightweight, high performance helmet, perfect for the riders pushing their limits. High-G. Low-G. Rotational. No matter what kind of impact, the ALPINE has you covered. The Alpine features LDL and Composite Fusion™ Plus technology. This helmet has you covered regardless of your discipline. With your helmet you will also find a breakaway visor, antibacterial pads and a helmet sock. Kali Protectives came from a breakthrough in safety technology - Composite Fusion, a process that bonds the helmet shell and foam enabling Kali to use a thinner shell, creating a lighter stronger helmet. Lighter and stronger means a safe helmet with less mass attached to your head.

Low density layer
Simply put, LDL started out with the idea of putting a low density liner inside Kali helmets to suck up the energy from a low-g hit to the head. Your helmet is there to take the beating for you when you hit your head, hard. LDL is there to soften the bumps you get that are not near the forces that compress or damage the foam in your helmet. It turns out that Low-g hits, especially when received repeatedly, turn into serious concussion damage to your brain.
The data shows the majority of impacts from accidents are happening at much lower-g forces than the standards are testing for. And thus Kali are huge advocates for getting softer materials into their helmets and closer to your head. The LDL reduces rotational impact forces up to 25%, and reduces low-g linear forces up to 30%.
Kali continues to test and experiment with materials and the design of LDL materials in the helmets and they won't stop. Afterall, they are an engineering driven company whose focus is developing the next generation of industry leading safety technologies.
COMPOSITE FUSION™ Plus - supreme impact absorbsion
While dozens of manufacturers in the powersport world utilize dual density foams, they are generally assembled like the layers of a cake. The COMPOSITE FUSION™ Plus Technology uses a layer of multi density cone shaped foam that intersect with a layer of softer foam that surrounds the head. In an impact, these cones act as a progressive damper to absorb different levels of impact. As they collapse, these cones also direct energy sideways and away from the brain.
A thinner shell allows impact G forces to dissipate more effectively into the energy-absorbing foam, eliminating the double spike in G's inherent in other helmets.
Lighter, Smaller, Safe. That's what Kali does.
Lifetime crash replacement
You crash it. Kali replaces. It's that simple. Kali doesn't do this as a marketing stunt or because they have lost their minds.
Kali does this because what they learn from crashed helmets informs everything they do. Kali has you return your crashed helmets so they can take them back into the lab to cut them open, measure them, and dissect them. Then they use the information they gather from the unlucky few who test these helmets in ways they cannot recreate to build the next generation of Kali helmets.
Of course, Kali prefers you never have to use the Lifetime Crash Replacement policy and suggest you replace your Kali helmets at respectable intervals. Let them reiterate once again, please leave the testing to Kali.
Kali® is an award-winning rider-owned company with technology-driven head and body protection for bike, snow, and powersports. With years of experience in product development and appliance of revolutionary technology, the company manages to create many state-of-the-art helmets. It offers innovative Composite Fusion helmets offering better impact energy management and increased dynamic range. Kali provides Low-Density Layer helmets reducing rotational impact forces by up to 25% and low-G linear impact forces by up to 30%. The company also boasts its Nano Fusion helmets which dissipate impact energy more efficiently in a smaller volume.
