The difference between a "hat" and a "helmet" is that a helmet is made specifically for protection. People such as police officers, sportsmen, soldiers, and more where a helmet for protection. Whereas a "hat" doesn't have as much padding and is used for style or just protection from the sun. Ex: If you're going to ride your bike, you need to get your helmet. Ex: I need a hat to complete this outfit.
