OUTDOORMASTER Bicycle for and Meets CPSC and ASTM Safety 3D Protective Bonus Replacement Removable and Perfect for and Ice Girls and Boys Kids'

√ [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 injuries. The inner shell of the 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. √ [All-round 3D protective cushion + replacement cushion included] The helmet is equipped with a thick, soft cushion inside, providing all-round protection for the forehead, back, sides, and top of the head. Made of porous material, it has good sweat absorption and can be removed and washed. It also comes with replacement cushions (forehead and back), which easily solves helmet hygiene issues and ensures long-term use. √【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 and omnidirectional adjustment of the side ears, under the chin, length, and head circumference. √ [Improved Asian-specific oval helmet] Currently, most European and American-style helmets on the market are oval 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 European or American-style helmet puts pressure on the temples, making it uncomfortable to wear. Our engineers spent a year developing a round-shaped helmet specifically for Asian children. It perfectly fits the Japanese head shape, providing a comfortable fit and better overall head protection. √ [CPSC Safety Standard + ASTM Safety Standard + 12-Month Warranty] CPSC standards are considered one of the safety standards for helmets sold in the United States and around the world.
