"I never play without my lucky cap.
It's become a bit of a superstition for me."
~Rory McIlroy

Caps are a type of headwear that have become an important part of many people's attire, including athletes such as golfers. There are several reasons why many golfers wear caps while playing golf. 

Sun Protection
The most common reason is to protect their face and eyes from the sun. Golfers often spend several hours on the golf course, which means prolonged exposure to the sun. A cap helps to shield their face and eyes from the harmful UV rays.

Improved Vision
A cap also helps golfers to improve their vision by reducing glare. The brim of the cap helps to shade the golfer's eyes from the sun and other bright light sources, which can improve their ability to see the ball and their surroundings.

Style
Golf caps have become a tradition and a fashion statement in golf culture. Many golfers wear caps as part of their uniform or to showcase their personal style. Caps come in a variety of colors, designs, and styles, and golfers can choose a cap that matches their outfit or represents their favorite golf brand.

Tradition
Wearing a cap is a tradition in golf culture. Many golfers wear caps as part of their uniform or to show their support for their favorite golf brand. It is also seen as a way of respecting the traditions of the game.

Comfort
A cap can help to keep a golfer's head cool and dry in hot and humid conditions. It can also help to keep sweat out of the eyes, which can be distracting and uncomfortable during play.
