Human: I'm trying to learn about a new type of hat called the “bowler” hat. Can you tell me more about it? Assistant: 
A bowler is a type of hat that has a rounded crown and flat brim. It was originally designed for men, but today it's popular with both sexes. The shape of a bowler hat makes it easy to wear in all kinds of weather, and it can be worn at work or play. Bowlers are often associated with sports teams, such as baseball and cricket players, and they are also commonly seen on politicians and businessmen.
