What is the Spanish term for 'Helmet'?

The Spanish term for 'Helmet' is 'Casco.' This term specifically refers to a protective headgear typically used in various contexts, such as sports, construction, or motorcycle riding. The use of 'casco' is widely recognized across Spanish-speaking countries and is synonymous with safety helmets designed to absorb impact and protect the skull.

The other terms provided do not relate to head protection. For instance, 'capucha' translates to 'hood,' which is a part of clothing but does not serve a protective function like a helmet. 'Sombrero' means 'hat' and usually refers to traditional wide-brimmed hats, particularly those associated with cultural or fashion statements rather than safety. 'Chaleco' translates to 'vest,' which is a garment worn on the upper body, completely unrelated to headgear.

Understanding these terms can be helpful in distinguishing between different types of headwear and their specific purposes in conversation or study of the Spanish language.
