A ski mask, also known as a balaclava, is a type of headwear designed to provide warmth and protection from cold weather. Typically made from materials like wool or synthetic fabrics, it covers the head, face, and neck, leaving only the eyes, mouth, and sometimes the nose exposed. Ski masks are commonly used in winter sports, such as skiing and snowboarding, as well as for outdoor activities in cold climates. These masks are popular among outdoor enthusiasts and winter athletes because they help retain body heat and shield against wind and snow. While they are practical for warmth, ski masks have also been associated with anonymity, leading to their use in various contexts beyond sports.
