/kloc-at the beginning of the 0/9th century, sun hats replaced painted sailor hats and became popular in navies all over the world. Sailor's hat has no brim, mainly to prevent the brim from going for a ride when the ship is sailing at high speed and damaging the instrument when using the observation instrument; The hard brim ring of the nautical hat can protect the sailors' heads so that they will not be hurt by bumps at sea; The streamer of the ocean hat can be used as both a weather vane and a tie to prevent the hat from falling off. There is another story about the origin of sailor hat ribbon, although it was mainly used to test the wind direction in the early days. 1805, Napoleon's army invaded Britain, and Nelson, commander-in-chief of the British navy, led the fleet to fight fiercely with the French fleet and defeated Napoleon's fleet. In the war, General Nelson was seriously injured and died. When the Royal Navy observed a moment of silence for him, all the sailors put two pieces of black gauze on the suffix of their hats to show their condolences and respect. Since then, the hats of British naval soldiers have been formally decorated with two black ribbons. Because of its wind measuring and decorative functions, streamers are gradually imitated by navies all over the world.

At present, the marine caps of all countries in the world are roughly the same, but some countries are slightly different. There is an obvious difference in the French navy hat, that is, the top of the navy hat is decorated with a particularly bright red pompon. It is said that the pompon is a part of the standard marine uniform stipulated by the French Ministry of Defence, which symbolizes "a drop of blood" and means "fighting bravely and not afraid of sacrifice". The sailor hat with a red ball at the top is very spiritual and easy to attract attention, so it is deeply loved by French sailors. Speaking of red velvet balls, there is another interesting origin. Due to the low cabin, the wooden warships of the ancient French navy often hit the wall. In order to prevent the head from being broken, the sailors put a ball of cotton yarn in their hats. Even so, some cotton yarns were bruised and stained with blood and turned into red balls. After several years of evolution, the French navy began to put a red fluffy ball on the top of sailors' hats, which means "good luck, you won't break your head." Nowadays, although the cabins of modern warships are not in danger of breaking their heads, the red pompoms on the top of the caps of the French navy still exist. Now, the red velvet ball on the top of sailor hat has not only become the decoration of French sailor suit, but also become their favorite mascot and collection.
