The Ketone XL Performance Hat is engineered for athletes who demand gear that works as hard as they do. Built with water- and sweat-repellent tech, it stays dry through intervals, long runs, and heat waves. Laser-cut ventilation keeps airflow high, while the moisture-wicking interior keeps you cool and comfortable. A lightweight, floatable bill and performance snapback closure deliver all-day durability. Designed for training, adventure, and everything in between.
