Unused I purchased this helmet this spring when it became mandatory to wear bicycle helmets, but I have never used it. 【Aerodynamic Design】 This helmet has an aerodynamic shape that minimizes wind resistance, making it ideal for cyclists seeking speed. 【Breathability】 Multiple ventilation holes are provided to maintain comfort even during long hours of use. You can enjoy riding while feeling cool even on hot days. 【Lightweight Material】 Made of lightweight plastic, it is less tiring to wear for long periods and provides a comfortable fit. - Color: Two-tone white and black - Design: Aerodynamic design - Ventilation holes: Multiple - Material: Lightweight plastic Thank you for viewing.
