The uvex i-vo 3D is at home in any terrain. Whether on a road bike or mountain bike, it fully showcases its strengths and safely accompanies both beginners and advanced riders on their biking tours. With 24 ventilation openings, the helmet provides optimal climate management, both when climbing and descending. The 3D-IAS-3.0 size adjustment system allows it to be tailored in height and width to fit any head. Weighing just 225 grams, it is also a true lightweight, making it comfortable for longer rides. The insect net reliably protects against unwanted intruders, and with an optionally available Triangle LED, it is even equipped for urban streets at dusk. The protective material EPS is directly foamed into the polycarbonate shell, allowing for a lightweight helmet construction with maximum impact resistance, providing the perfect fusion of EPS inner layer and PC outer layer. The uvex IAS system allows for width adjustments of the helmets. After all, everyone has their own unique head shape. Heads vary not only in circumference but also in height. Therefore, the uvex IAS-3D system offers the additional option for precise adjustment to individual head height.
