The Lazer Z1 KinetiCore is a featherweight road helmet that pairs class-leading airflow with built-in rotational impact protection, so you stay cool, comfortable and confident on every ride. At just 220g in a size Medium, it all but disappears on your head while earning a 5-star Virginia Tech safety rating — no separate MIPS liner required.

Highlights

• Ultralight at 220g (size M): one of the lightest certified road helmets available, ideal for long days in the saddle.
• KinetiCore rotational protection: Controlled Crumple Zones are engineered directly into the EPS foam, absorbing and redirecting both direct and rotational impact energy.
• 5-star Virginia Tech rating: independent testing confirms top-tier protection without relying on a secondary liner.
• 33 ventilation ports: generous venting with a floating headband channels air across your scalp for best-in-class cooling efficiency.
• Advanced RollSys fit system: a single thumbwheel on top of the helmet adjusts the full-circumference headband on the fly — ponytail-friendly by design.
• Polygiene StayFresh padding: Biostatic technology on straps and padding inhibits odour-causing bacteria, keeping the helmet fresher ride after ride.
• Eyewear-friendly dock vents: updated rear basket and side channels let sunglass temples sit neatly without pressure.
• Aeroshell and LED compatible: accepts the optional Lazer polycarbonate Aeroshell for cold or wet weather, plus a universal Lazer LED taillight mounts to the rear.

Protection that moves with you

KinetiCore integrates Controlled Crumple Zones — EPS foam blocks precision-engineered into the helmet structure — that absorb and redirect energy from both direct and rotational impacts. Because the protection is built into the helmet rather than added as a separate liner, the Z1 KinetiCore is 24% lighter than the previous Z1 MIPS, using 70g less material, without compromising on certified safety.

Cool, comfortable and quiet

Thirty-three vents combined with a floating headband design actively channel airflow across the scalp when the pace lifts. The Advanced RollSys system wraps the full circumference of the head and fine-tunes with a single thumbwheel on top — making mid-ride adjustments easy, and leaving room for a ponytail without any uncomfortable pressure points.

Stay fresh, ride after ride

Polygiene StayFresh treatment on the removable padding and Biostatic technology woven into the strap material inhibit the growth of odour-causing bacteria. The lightweight straps lie flat and the updated rear basket accommodates sunglass temples cleanly, making it simple to dock your eyewear without fumbling.

Compatibility & fit

This is a size Medium, suitable for head circumferences of 55–59cm. The Z1 KinetiCore accepts the optional Lazer Aeroshell (available in S/M/L) for cold or wet-weather riding and aerodynamic gains, and a universal Lazer LED light mounts directly to the rear. Certified to both CE/EN 1078 (European) and CPSC (US/Australian) safety standards. Colour: Harbor Grey.
