Rotational impact protection typically adds weight and blocks airflow. Lazer's KinetiCore technology takes a different approach by building protection directly into the EPS foam structure rather than layering a plastic slip-plane underneath. The result drops 40 grams from the previous Z1 MIPS while earning the same Virginia Tech 5-star safety rating. Controlled crumple zones molded into the foam absorb energy from both direct and rotational impacts, collapsing in a crash to redirect force away from your head.

The weight savings come from using less material overall. KinetiCore eliminates the plastic liner and its mounting hardware, reduces total EPS volume, and integrates the protection system into the helmet's fundamental structure. At 220 grams in a size medium, the Z1 KinetiCore sits among the lightest road helmets with rotational protection available. Lazer claims 24% lighter construction than the Z1 MIPS with 70 grams less plastic in the manufacturing process.

Ventilation benefits from that same streamlined approach. Without a plastic layer blocking airflow between foam and scalp, air moves through the helmet more efficiently. Strategically placed vents and internal channels pull air from the front openings across your head and out the rear exhaust ports. A floating headband at the forehead lifts away from skin contact to create additional airflow space while keeping the fit comfortable during hard efforts. Lazer rates the cooling efficiency at 103%, meaning the helmet actually cools your head slightly more than going bare.... Read More
