The Lazer Vento KinetiCore is a full-performance aero road helmet built for riders who refuse to compromise between speed, ventilation, and protection. Designed at a 15-degree sprint angle to minimise frontal drag, it integrates KinetiCore rotational impact protection directly into the EPS foam — no add-on liner required — making it 24% lighter than its predecessor with 90g less plastic. If you ride fast and want to stay cool, comfortable, and protected, this is the helmet.

Highlights

• KinetiCore protection: Strategically shaped EPS foam crumple zones absorb both direct and rotational impact forces without the weight penalty of a separate MIPS liner.
• Virginia Tech 5-star rated: Independently tested and awarded the highest safety rating by Virginia Tech's helmet lab.
• Venturi ventilation: 13 vents work via the Venturi effect — smaller front intakes pressurise airflow through internal channels, actively expelling heat through rear exhaust ports. Runs 5.4% cooler than the Bullet 2.0.
• Aerodynamic shell: Optimised at a 15-degree sprint angle for maximum drag reduction; 2.3% faster than the previous Vento generation.
• ScrollSys fit system: A floating front headband paired with a horizontal scroll-belt retention system distributes tension evenly, eliminates pressure points, and allows mid-ride adjustments.
• Eyewear docking: Silicone-lined slots in the front vents securely park sunglasses when not on your face.
• Polygiene Biostatic padding: Stay-fresh antimicrobial treatment keeps the interior liner fresher for longer.
• LED light compatible: Integrates with Lazer's Universal LED Helmet Tail Light (sold separately).

KinetiCore Technology

Rather than layering a separate slip-plane liner inside the helmet, Lazer's KinetiCore system shapes the EPS foam itself into controlled crumple zones. On impact, these zones deform and break in a controlled manner to redirect rotational energy away from the brain — delivering equivalent or better protection with less mass and fewer components. The result is a simpler, lighter, and more environmentally responsible helmet that still earns a five-star Virginia Tech safety rating.

Ventilation & Aerodynamics

The Vento's 13-vent layout uses the Venturi effect to actively accelerate airflow rather than relying purely on wind passing through. Smaller front intake ports create elevated air pressure that drives cooler air through internal channels and forces warm air out through rear exhaust ports — keeping your head noticeably cooler on climbs and in hot conditions. The aero shell is designed at a 15-degree angle matching a real-world sprint or TT position, so the aerodynamic benefit is realised where it actually counts.

Fit & Sizing

This listing is for size Large, fitting head circumferences of 58–62cm. The ScrollSys retention system uses a horizontal belt and floating front headband to spread clamping force evenly around the head. The system adjusts easily while riding and suits a wide range of head shapes without creating the hot-spots common to traditional dial-retention designs. Sizing: S 52–56cm, M 55–59cm, L 58–62cm.
