We recommend many outdoor sports such as mountain climbing, pedal cycling, skating, trekking, and parachuting. Helmets are necessary to safely enjoy various sports. ⚫︎ Good Ventilation On the helmet. Designed with 11 holes for good ventilation and cooling effect, creating airflow inside. Customers who tend to sweat on their heads will feel refreshed. ⚫︎ Lightweight This product for children is ultra-lightweight at approximately 230g, effectively reducing the burden on the head and making it less tiring even after long use! It's also convenient to carry. ⚫︎ Hard ABS + High-Density EPS The outer shell uses hard ABS material, which has rigidity, hardness, and impact resistance, and high-density EPS, which also has excellent shock absorption, is used as the inner shell of the sports helmet.
