A "chaleco" is a type of vest commonly worn as a garment. It is typically sleeveless and can be made from various materials, including cotton, wool, or synthetic fabrics. Chalecos are often used for layering, providing warmth without restricting arm movement. They can be found in both casual and formal styles. In some cultures, chalecos are also associated with traditional attire. For example, in Latin America, they may be worn as part of folk costumes during festivals. Additionally, chalecos are popular in outdoor activities, such as hiking or fishing, where they may feature pockets for carrying essentials.
