1. The earliest baseball cap
In 1849, the New York baseball team in the United States issued uniform caps to players for the first time. This cap has no brim and is more like the current cap, which is mainly used to distinguish the players of the two teams.
2. The birth of the brim (1860)
As baseball developed, players found that the sun would affect their vision. Around 1860, the brim was added to the design to help players block the sun.
3. The prototype of the modern baseball cap (1901)
In the early 20th century, baseball caps began to look like what they are now:
Hard brim
Adjustable elastic band
More rigid cap shape
In 1901, after the establishment of Major League Baseball (MLB), each team began to design caps with team logos, and baseball caps gradually became part of the team culture.

4. From sports equipment to trendy items (after the 1970s)
In the 1970s, baseball caps began to go beyond the court:
Hip-hop culture led to the trend of wearing baseball caps backwards
Street enthusiasts turned baseball caps into fashion accessories
Brands began to launch baseball caps of various materials
5. Baseball caps today
Modern baseball caps have developed a variety of styles:
Flat brim caps: street fashion style
Curved brim caps: traditional sports style
Trucker caps: mesh back brim design
Dad caps: loose retro style
