Push harder on every descent. The Lazer Chase KinetiCore is a lightweight full-face mountain bike helmet built for gravity disciplines — downhill, enduro, and bike park — where ASTM downhill certification and tested rotational impact protection meet genuine all-day comfort.

Highlights

• KinetiCore integrated protection: Controlled crumple zones built directly into the shell absorb both direct and rotational impact forces without added bulk or a separate MIPS liner.
• ASTM DH certified: Meets the highest downhill racing standard; also certified to AS/NZS, CE/EN, and CPSC standards for global compliance.
• Virginia Tech 5-star rated: Independently awarded "Best Available" protection by Virginia Tech's helmet testing programme.
• Breakaway visor: Engineered to release under impact forces, reducing the rotational energy transferred to your neck during a crash.
• 11 integrated vents: KinetiCore channels double as ventilation pathways, keeping airflow moving on steep, technical trails.
• Double D-ring closure: Race-proven chin strap buckle stays locked on aggressive terrain and is simple to adjust with gloves on.
• Neck brace compatible: Designed to work seamlessly with leading neck brace systems for riders who want maximum protection.
• Plush sweat-wicking liner: Removable and washable padding for comfort and hygiene on long sessions.

KinetiCore technology

Unlike helmets that add rotational protection as a separate internal layer, KinetiCore integrates controlled crumple zones directly into the EPS foam during manufacturing. These structured zones compress and flex on oblique impacts, managing rotational acceleration before it reaches your brain — with no extra weight, no separate liner to move around, and no compromise to direct-impact protection.

Build quality

The Chase shell combines EPS foam with a polycarbonate outer, reinforced with fibreglass, carbon fibre, and nylon for a construction that balances stiffness, impact resistance, and a weight of approximately 990g (size M). The Matt Dusty Blue colourway gives it a clean, understated look on the hill.

Compatibility & fit

Size L fits a head circumference of 58–60cm (22.87–23.63"). Measure around the widest part of your head, just above the eyebrows, before ordering. The Chase is neck-brace compatible with major systems. Always replace a helmet after any significant impact. Includes a carrying bag.
