Aero helmets traditionally force a choice: accept the heat buildup that comes with reduced venting, or sacrifice aerodynamic gains for airflow. Lazer developed the Vento KinetiCore in collaboration with professional teams to close that gap, engineering a helmet that tests 2.3% faster than its predecessor while running 5.4% cooler. The reduced frontal surface area cuts drag when your head drops into a sprint position at 15 degrees, which is where Lazer optimized the shape during wind tunnel development.

Ventilation comes through a Venturi effect system that accelerates airflow through the helmet. Smaller intake vents at the front create higher air pressure that pushes through internal channels and expels hot air faster through the rear exhaust ports. The physics work with you rather than against you: moving faster increases the pressure differential and improves cooling exactly when you're generating the most heat. Thirteen vents total handle the airflow management, and a floating front headband lifts away from your forehead to create additional circulation space while eliminating pressure points.

KinetiCore handles impact protection by building controlled crumple zones directly into the EPS foam structure. Where traditional rotational protection systems add a plastic slip-plane layer inside the helmet, KinetiCore shapes the foam itself into strategically placed blocks that deform and break under impact to absorb energy. This integrated approach eliminates 90 grams of plastic compared to the Bullet 2.0 it replaces, drops total weight by 24%, and opens internal airflow channels that would otherwise be blocked by a liner. Virginia Tech awarded the Vento KinetiCore a 5-star safety rating in their independent testing.... Read More
