Tactical boonie hat is designed for hot weather. It protects well from the sunlight and overheating, and allows you to stay outdoors longer.
Boonie hat dries quickly and does not lose its shape, even if it has to be folded and hidden. The wide brim prevents the skin on your face and neck from getting burned.
There are additional holes for air ventilation. To prevent the boonie hat from flying off, there is a clip-on string under the chin.
