The OF Invader is purpose-built for modern trail riders who demand more than a standard half shell. With deeper coverage, optimized ventilation, and Kali’s proven Composite Fusion™ technology paired with a RHEON® Low Density Layer, it delivers lightweight strength and impact protection in an open-face design. Confident, breathable, and ready for bigger trails—the OF Invader keeps you moving with freedom and security.
The OF Invader is built with Composite Fusion™, a process that fuses the helmet shell and foam, allowing for a thinner shell that’s both lighter and stronger. To further enhance protection, it features a RHEON® Low Density Layer (LDL), which helps reduce non-linear and rotational impacts. Designed with deeper coverage and increased ventilation compared to a standard half shell, the OF Invader is made for today’s riders who are tackling bigger bikes and bigger trails.
As Kali founder Brad Waldron puts it: “Our bikes are better, our trails are bigger, and our protection needs to keep up. The new OF Invader is designed with deeper coverage and better ventilation than a standard half shell helmet, so riders are ready for whatever the trail offers.”
