Using an upgraded pure EPS integrated molding technology with a commercially available ABS + EPS structure, the impact is distributed throughout, minimizing damage to the helmet and head. 100% pure EPS is used, increasing density and impact resistance. Furthermore, it is about 30% lighter than the overall ABS + EPS structure. "Road bike and MTB compatible" The visor is removable, allowing you to freely switch between a road bike helmet and a (MTB) mountain helmet. The 3-in-1 all-around adjuster system allows for fine adjustments in all directions for the side ears, under the chin, length, and head circumference. "Night LED light" By equipping the helmet with a bright LED light, there is no need to add a tail light to the bicycle. Including 3 modes (long light, flashing, flash), you can get excellent visibility at night from pedestrians, cyclists, and car drivers, avoiding dangerous contact and enjoying safer cycling. "Stylish ventilation design" With a design of 11 ventilation holes, the airflow is good, allowing for easy heat dissipation and cooling, keeping your head feeling refreshed. Cushions are attached inside the helmet, and porous materials are used for good sweat absorption, and they can be removed and washed. Size: 52cm - 58cm 8-31
