Sombrero

Sombrero (Spanish for "hat", literally "shadower") in English refers to a type of wide-brimmed hat popularly worn in Mexico, used to shield from the sun. It usually has a high pointed crown, an extra-wide brim (broad enough to cast a shadow over the head, neck and shoulders of the wearer, and slightly upturned at the edge), and a chin string to hold it in place. Cowboys generalized the word to mean just about any wide broad-brimmed hat.

Sombreros, like the cowboy hats invented later, were designed in response to the demands of the physical environment. The concept of a broad-brimmed hat worn by a rider on horseback can be seen as far back as the Mongolian horsemen of the 13th century. In hot, sunny climates hats evolved to have wide brims, which provided shade. The Spanish developed a flat-topped sombrero, which they brought to Mexico. It was modified by the vaquero into the round-crowned Mexican sombrero and poblano. Although sombrero is usually taken to refer to the traditional Mexican headwear, the term sombrero predates this item of clothing, and is and has been applied to several differing styles of hat, since it is the actual word for hat in Spanish. Other types of hats known as sombrero can be found in South America and Spain, including the sombrero calañés, sombrero cordobés and sombrero de catite (Spain), sombrero vueltiao (Colombia).

Many early Texan cowboys adopted the Spanish and Mexican sombrero with its flat crown and wide, flat brim. Also called the poblano, these hats came from Spain.

The Mexican variation of the sombrero added an even wider brim and a high, conical crown. These are the hats worn by mariachi musicians and charros. Both types of sombreros usually include a barboquejo or chin strap.

In the Western United States, the sombrero had a high conical or cylindrical crown with a saucer-shaped brim, highly embroidered and made of plush felt.
