The inside uses EPS material with excellent impact absorption, and the integrated molding technology disperses and absorbs impact to the maximum extent, protecting the head from all directions.

The side ventilation holes are upgraded, and the reverse airflow structure effectively prevents heat and sweat buildup, providing a constantly refreshing wearing experience. It is a versatile helmet that can be used in many scenes, such as commuting to school, commuting to work, road biking, and everyday cycling. [Optimized for Japanese Head Shape + Stable Fit Design] Unlike the oval design of European and American products, it adopts a 3D fit structure based on data of Japanese head shapes for bicycle helmets. With 3-point support on the forehead, temples, and back of the head, it prevents slippage and shaking during riding, and the low-center-of-gravity design gives a stylish impression. The back of the head is equipped with a buckle-type dial adjustment function from the American ITW brand, allowing for fine adjustments with one hand and accommodating head circumferences of 56-61cm (SG certification test range: 58-61cm). [Reliable Warranty from a Japanese Company + High-Quality Materials] The chin strap adopts a double-braided structure to reduce skin irritation from friction and improve the wearing comfort.
