Fit & Design: Integrated Visor: More than just a pretty piece, the integrated visor on the Lupo stays put when you’re moving fast and doesn’t snap off easily when you come to a stop too quickly. Guaranteed to Fit: “One size fits all” is now reality. We designed the sweet-looking visor, helmet shell and fit system to accommodate a wide variety of head sizes and shapes. Eyewear Friendly: We removed plastic to make space for your shades, leaving a comfortable spot to park those sunglass arms. Because a good riding day in the sun shouldn’t hurt your head. LED light compatible: Increase visibility by attaching the Universal Lazer LED to the mount at the back of the helmet. Winter Kit compatible: For those brisk winter rides, add the soft fleece Winter Kit for a cold weather conversion that keeps you powering through all year round. (Kit not included with helmet.) Technology: More Protection. Less Plastic: Lazer KinetiCore is the world’s first responsibly designed and fully integrated impact protection technology, and still saves up to 12.82% plastic in the construction process.
