High-density EPS, which is lightweight, has excellent insulation and water resistance, and also has excellent shock absorption, is used as the inner shell of the sports helmet, adding to the safety of the head in the event of a fall. 【All-around 3D Protection Cushion + Replacement Cushion Bonus】 The inside of the helmet is equipped with thick and soft cushions, protecting the forehead, back of the head, temples, and top of the head from all directions. The use of porous materials also provides 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, easily solving the helmet's hygiene issues and allowing for long-term use. 【12 Ventilation Holes + 3-in-1 Adjuster System】 With a design of 12 ventilation holes, the airflow is good, 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 side ears, under the chin, length, and head circumference from all directions.
