Most people show their loyalty to teams or accentuate their attire by wearing these hats, but there is a story being the bobble. The sailor hats of French marines had this bobble to prevent injuries on cabin ceilings. The soft fur protected the head from blows and acted as a sign of danger if the bobble grazed across one’s scalp. Later, the bobbles were used to distinguish the different military branches from each other based on shape, size, and color. Later, the name changed to pompoms.
