The sailor cap, or skullcap, has historically been one of the world's most widespread types of headgear. The cap has no shade and is therefore suitable at sea, because the wind has no shade to grab onto. Among musicians it is often called a Jazz cap.
The round and simple shape is widespread and some claim that the shape dates back 3.3 million years to the oldest stone age.
