hat

Abstract

This article is a hat with breathability and heat insulation. The crown of the hat is made up of an outer crown part and an inner crown part, and the crown part is provided in two layers. A slip is provided on the inner side of the inner crown part. The side crown of the outer crown part and the entire crown of the inner crown part (side crown, top crown) are made of mesh fabric. As shown in the reference diagram explaining each part, the space between the outer crown part and the inner crown part functions as a ventilation part. In addition, by making the top crown of the outer crown part out of heat insulation fabric, the heat insulation of the top of the head can be improved.
