Outdoor Master helmet. Color is light blue. Size is S (46-52cm). Used twice. No history of falls. It's in good condition with only a few scratches. The helmet was likely manufactured in 2020. What I'm selling is the helmet in the picture and replacement cushions (unused). Product information below: S size 46cm-52cm 【Hard ABS + High-Density EPS】 The outer shell uses ABS, which has an excellent balance of mechanical properties such as rigidity, hardness, processability, impact resistance, and bending fatigue resistance, and can effectively reduce impact and prevent external injuries. High-density EPS, which is lightweight and has excellent heat insulation and water resistance, as well as impact absorption, is used as the inner shell of the sports helmet, adding safety to the head in the event of a fall. 【All-around 3D protective cushion + replacement cushion bonus】 Thick and soft cushions are attached to the inside of the helmet, protecting the forehead, back of the head, temples, and top of the head from all directions. The porous material is used for good sweat absorption, and it can be removed and washed. Furthermore, a replacement cushion (for the forehead and back of the head) is included as a bonus, making it easy to solve the helmet's hygiene problem and allowing for long-term use. 【11 ventilation holes + 3-in-1 adjuster system】 With a design of 11 ventilation holes, air flows well, allowing for easy heat dissipation and cooling, keeping the head feeling refreshed. The evolved 3-in-1 all-around adjuster system allows for fine adjustments to the sides of the ears, under the chin, length, and head circumference from all directions. 【Improved model specifically for Asia】 Most helmet models on the market are European and American models (oval), because European and American children have long heads (narrow width and protruding back of the head). However, Asian children have short heads (wide width and flat back of the head). Wearing European and American models can compress the temples and make the fit uncomfortable, so our engineers spent a year developing a model (circular) specifically for Asian children. It fits the Japanese head shape more perfectly, providing a comfortable fit while better protecting the entire head. 【CPSC safety standards + ASTM safety standards】 The CPSC standard is a safety standard considered as one of the standards among helmets distributed in the United States and around the world. The ASTM standard is the American Society for Testing and Materials, the world's largest standardization organization.
