[Hard ABS + High-Density EPS] The outer shell is made of ABS, which has an excellent balance of mechanical properties such as rigidity, hardness, processability, impact resistance, and bending fatigue resistance, reducing impact and preventing external injuries. The inner shell of this sports helmet is made of high-density EPS, which is lightweight, insulating, water-resistant, and has excellent shock absorption properties, providing added head safety in the event of a fall. [Adjustable Size] Size S: Head circumference 51cm-54cm (Recommended age: 3-8 years old) Size M: Head circumference 55-58cm (Recommended age: 8-13 years old) The helmet comes with a dial adjustment screw, so you can adjust the helmet size to fit your child's head circumference. The one-touch chin strap makes it easy for children to put on and take off. Please be sure to check the size before ordering. [Improved Asian-specific headrest] Currently, most helmets on the market are oval-shaped (European and American-style) because European and American children have long heads (narrow width and protruding back). However, Asian children have short heads (wide width and flat head). Wearing a Western-style headrest puts pressure on the temples, making it uncomfortable to wear. Our engineers spent a year developing a round-shaped headrest specifically for Asian children. It perfectly fits the Japanese head shape, providing a comfortable fit and better overall head protection. Lightweight: Weighing approximately 300g, this ultra-lightweight helmet reduces head strain and provides comfort even when worn for extended periods. Ideal for preventing injuries while riding a bicycle, skateboard, kick scooter, or inline skate. [11 Ventilation Holes + 3-in-1 Adjuster System] The 11 ventilation holes allow for good airflow, allowing for easy heat dissipation and cooling, keeping your head fresh. The improved 3-in-1 omnidirectional adjuster system allows for precise adjustments to the side ears, under the chin, length, and head circumference in all directions.
