Built for riders who push hard on descents and bike park laps, the Lazer Chase KinetiCore is a lightweight full-face mountain bike helmet that delivers downhill-certified protection without sacrificing all-day comfort. KinetiCore controlled crumple zones are built directly into the shell — no separate liner insert needed — absorbing the energy from both direct and rotational impacts to protect what matters most.

Highlights

• KinetiCore rotational impact protection: Integrated EPS crumple zones redirect energy from both direct and rotational impacts away from your head — built in, not bolted on.
• ASTM DH certified: Meets ASTM 1952 downhill standard as well as CPSC and CE EN 1078, giving you confidence in the most demanding gravity disciplines.
• Breakaway visor: Designed to separate cleanly during an impact to minimise rotational forces on the neck, while still shielding eyes and face on trail.
• 11 ventilation channels: KinetiCore channelling draws air inside the helmet and flows it across your head to keep you cool through long lift-served days.
• Double D-ring closure: Reliable, race-proven buckle system stays secure and won't rattle loose mid-ride.
• Neck brace compatible: Designed to work with leading neck brace systems for riders who want an additional layer of safety.
• Plush sweat-wicking liner: Removable and washable padding keeps the fit fresh across repeated sessions.

KinetiCore Technology

Rather than adding a separate rotational protection insert, Lazer engineered KinetiCore directly into the helmet's EPS foam. Controlled crumple zones are strategically positioned around the shell so that under impact the foam deforms in a calculated way, absorbing and redirecting energy — both the linear force of a direct hit and the rotational forces that can cause serious brain injury. The result is a helmet that is cleaner, lighter, and no thicker than a conventional full-face, with protection built to a higher standard.

Construction

The Chase KC combines a polycarbonate outer shell with a multi-density EPS foam body incorporating fiberglass and carbon fibre reinforcement elements where structural rigidity matters most. The flexible front grid protects the face from trail spray and debris while maintaining airflow. The Matte Moss colourway gives the helmet a distinctive low-key finish that reads well both on trail and at the uplift.

Compatibility & Fit

This listing is size S, suitable for head circumferences of 54–56 cm. Measure around the widest part of your head (just above the eyebrows) and consult the Lazer size chart before ordering. The Chase KC is compatible with leading neck brace systems. Certifications: CPSC, CE EN 1078, ASTM 1952 (downhill). Always replace a helmet after any significant impact.
