It cuts the scorching sun outside and protects you from the cold of the air conditioning indoors. Because it's made of quick-drying material, sweat dries quickly, so you won't get chilled by the air conditioning after sweating outside. I think it can also be used as an inner layer for mourning clothes in winter. I wanted to wear it again this year if I hadn't outgrown it, but I'm reluctantly letting it go.
