Straw Hat

A straw hat (麦わら帽子 or 麦わら)can refer to any brimmed hat that is woven out of straw. This hat is designed to protect the head from the sun, as well as protect against heatstroke. There are several styles of straw hats, but all of them are made of woven straw. Many of these hats are formed in a similar way to felt hats; they are softened by steam or by submersion in hot water, and then formed by hand or over a block. Finer and more expensive straw hats have a tighter and more consistent weave. Since it takes much more time to weave a larger hat than a smaller one, larger hats are more expensive.

History
Straw hats have been worn consistently in Europe in the summer since antiquity, and arguably are the least-changed form of headgear, since many medieval examples would draw no special attention if worn today. Many are to be seen in the famous calendar miniatures of the Très Riches Heures du Duc de Berry, worn by all classes, mostly by men. The Middle Ages also produced, among the more fashionably dressed, possibly the most spectacular straw hats ever seen on men in the West, notably those worn in the Arnolfini Portrait of 1434 by Jan van Eyck (tall, stained black) and by Saint George in a painting by Pisanello of around the same date.

Monkey D. Luffy
In the manga and anime One Piece, Monkey D. Luffy's straw hat is the main symbol of the entire series and is the origin of his nickname "Straw Hat Luffy." His straw hat was given to him by his idol, Red Hair Shanks when he was a kid, and he promised to give the hat back to him once he becomes a great pirate (or in other words, the Pirate King). Much later, during the Straw Hat Pirates' departure for Fishman Island, it was revealed by Silvers Rayleigh that this straw hat originally belonged to Gol D. Roger.

Although Luffy's straw hat is his treasure, he is seen without it on occasion. This is usually because he does not want anything bad to happen to it. In which case, he usually gives it to another member of his crew for safe keeping. It has been damaged twice in the manga canon. The first time it was damaged by Buggy when he was fighting Luffy, and further spat on it when he learned it was Shanks'. After the fight, Nami repaired it for him. However, Luffy was overjoyed that Nami had repaired it, he poked it several times and accidentally made another hole in the repair work, causing Nami to hit him with the sharp end of the needle since it had been only a temporary repair; nevertheless, she repaired it again.

During the Alabasta Arc, when Ace leaves the Straw Hats and Vivi, he gives Luffy a "blank piece of white paper" (Vivre Card). Saving it from getting eaten by Eyelashes, Nami sews it into the red band near the brim of his hat.



Luffy's hat fell off when Jinbe, who was carrying him, was struck by Admiral Akainu. As Luffy was mentally shattered from his brother's death, he did not notice, nor did Jinbe, who was occupied with dealing with the Admiral. After Shanks appeared, the straw hat was reunited with its old owner after over ten years. Shanks convinces Buggy to return the straw hat to Luffy shortly after, and ended up in Trafalgar Law's temporary care. It was then handed over to Silvers Rayleigh, who in turn returned the straw hat to Luffy after he recovered. Prior to his training with Rayleigh at Rusukaina island, Luffy set aside the hat on the island's only safe location. He eventually picked it back up after the training is over.

Luffy's straw hat has somehow managed to survive through all his battles even when it logically could not possibly have done so, such as when he was poisoned by Magellan and was literally dissolving.

Oars Jr.
The kasa (conical straw hat) made by Ace was given to Oars Jr. as he believed it would help the giant since he was so close to the sun. Oars Jr. was so moved by this gift, he fought with all of his strength to save Ace during the Whitebeard War.

Demalo Black
Demalo Black, in a poor attempt to impersonate Luffy, also wears a straw hat. However, his was different by being frayed and unkempt, and having a striped band around its circumference. It fell off when Sentomaru smashed him on the head.

Fishman Island Children
After Luffy and his crew defeated the New Fishman Pirates and saved Fishman Island, children wanted to get straw hats so they could play hero. Despite the adults saying that straw hats can only be bought on the surface, Jinbe states that he will pick some up for them.
