Background

In hot summer, the hat can play a role in shading the sun, but when the hat is worn in hot summer, the head of a wearer sweats due to overhigh temperature, and discomfort or even heatstroke is caused. One reason for this is that under the direct irradiation of sunlight, the hat absorbs the sunlight and heats up continuously, resulting in excessive heat accumulation on the surface of the hat; another reason is that the temperature in the cap cavity is constantly increasing due to the constant heating of the wearer's head. Therefore, the traditional hat cannot reduce the temperature in the cavity and the surface temperature of the hat, and the thermal comfort of a user is poor.
