This lightweight cap uses Cool Dots material, which is water-repellent yet breathable thanks to its microscopic pores. The size can be finely adjusted with the head circumference adjuster and bungee cord on the back of the inner sweatband. It has a crushable structure that can be folded and stored in a pocket or bag, and it has a wire inside the brim that allows you to freely change its shape.
