Thank you for viewing. The Airpeak running cap features high-performance functionality, lightness, and water repellency. - Color: Black - Type: Running Cap - Style: Sports - Material: Water-repellent material - Features: Lightweight design ₌ Size: Free size (55-59cm) The "Flow System" ventilation system, AirpeakPRO, resulted in lower temperatures inside the cap compared to conventional running caps (white), with a measurement of 13°C for black and 15°C for white. The two-layer structure ensures airflow, providing not only a cooling effect but also making it difficult to come off even in strong winds, making it highly effective for sports that catch the wind, such as running and cycling. *Slight wrinkles present* *How about giving it as a gift to someone special, for either men or women?*
