Design & Features
The biggest story with the Jackal is the KinetiCore technology itself. In short, the goal is to allow the helmet to rotate slightly on the rider’s head when they hit the ground, to reduce the likelihood and severity of traumatic brain injuries. The idea is that, if the helmet shell can rotate somewhat, it’ll impart less force to the head by helping to mitigate the rotational acceleration that occurs due to the helmet not sliding 100% friction-free against the ground or whatever else you might be unfortunate enough to run into.
Traditionally, most technologies with that goal in mind — MIPS being the frontrunner in that space — have gone about the problem by adding a plastic liner between the helmet padding and the shell, which can rotate between the helmet shell and the rider’s head and provide a degree of movement there. But such a system has downsides — adding a plastic liner to the helmet adds weight, can block or otherwise limit ventilation, and in a lot of cases causes some noticeable movement of the helmet shell under normal riding conditions. And so Lazer went back to the drawing board and came up with KinetiCore — a deceptively simple way of taking on the same goal.
Instead of incorporating a plastic liner that can move all of the time, Lazer molded a carefully designed series of blocks and channels into the EPS foam shell (the standard expanded foam that most bike helmets are constructed from), which, due to the open channels, have room to deflect laterally in the event of a crash that imparts some rotational energy into the helmet. But by getting rid of the plastic liner, Lazer says that they’re able to cut a significant amount of weight, use less plastic in the helmet, improve ventilation, and do away with the feeling of the helmet moving on your head that you can get with MIPS.
