I've noticed a lot of people wearing baseball caps lately. What's the story with this?

The story is that it's become popular again, and people are buying them in droves! Baseball caps have been around since the early 1900s, but they were mostly associated with sports teams and casual wear until recently. In recent years, however, they've seen an upswing in popularity due to their wide range of colors, designs, and affordability. They're great for protecting your head from the sun, as well as keeping you cool in hot weather.
