The Lazer Z1 KinetiCore is a flagship road helmet built for riders who refuse to compromise on protection, ventilation, or weight. At just 220g, it pairs featherweight construction with Lazer's integrated KinetiCore rotational impact protection — no separate MIPS liner needed — making it one of the most advanced road helmets available for competitive and enthusiast cyclists alike.

Highlights

• KinetiCore rotational impact protection: Controlled crumple zones built directly into the EPS foam redirect both direct and rotational impact forces — no add-on liner, no added weight.
• Featherweight at 220g: One of the lightest helmets in its class, reducing fatigue on long days in the saddle.
• 33 vents for best-in-class airflow: Strategically positioned air intakes and inclined bridges deliver exceptional ventilation — independently tested to provide 3% more cooling than wearing no helmet at all.
• Advanced RollSys fit system: A thumb-wheel dial on the crown controls a retention cradle spanning the full circumference of the head, with vertical height adjustment for a locked-in, pressure-free fit.
• Floating headband: Keeps the brow contact-free, boosting comfort and allowing additional airflow across the forehead.
• Polygiene Biostatic™ padding: Antimicrobial treatment keeps the interior fresh across long training blocks and hot weather riding.
• Eyewear-friendly design: Rear basket accommodates sunglasses storage, with a ratchet height adjustment that also suits ponytail wearers.
• Aeroshell and LED light compatible: Optional polycarbonate Aeroshell closes the vents for time-trial conditions; universal rear LED mount included.

Construction

The Z1 KinetiCore uses an in-mould polycarbonate shell bonded to an EPS foam liner with KinetiCore crumple zones integrated at the point of manufacture. This construction delivers a torsionally rigid, lightweight shell while eliminating the need for a separate rotational impact layer. The result is a helmet that is lighter, simpler to maintain, and certified to both CPSC and EN 1078 (CE) safety standards.

Fit & Sizing

This listing is Size S, fitting head circumferences of 52–56 cm (20.5–22 in). The Advanced RollSys dial sits on the crown of the helmet and allows micro-adjustment without removing gloves. The rear basket adjusts vertically via a ratchet system to accommodate different head shapes and ponytail styles. Straps are effortless to adjust and lock flat against the face for a clean, chafe-free finish.
