From Lazer Helmet:
The Codax KinetiCore’s one size fits all design is quick to adjust with the spin of the TurnSys dial for a secure and comfortable fit in seconds. Lightweight and breathable, this helmet is fitted with insect netting on the front vents to keep bugs and other distractions out while you’re focused on the ride ahead. LED light compatibility makes it easy to attach the Universal Lazer LED (sold separately) to the back of the helmet, ensuring you’re seen in all light and weather conditions. This helmet is Winter Kit compatible (sold separately), offering increased warmth during those brisk rides with a simple swap of the original KinetiCore padding for a cozy fleece conversion that blocks cold breezes.
Pedal with confidence and leave the protection up to us. KinetiCore by Lazer is the world’s first responsibly designed and fully Integrated Rotational Impact Protection technology that’s built better by design; integrated right into the helmet instead of added on after, it delivers next-level protection while reducing weight and increasing ventilation. This helmet scores a “Very Good” 4-Star protection rating from Virginia Tech.
