Sun Hat is any hat or headgear specifically designed to shield the face, neck, and shoulders from direct sunlight, usually with a semi-rigid brim protruding from the circumference, which can be small to large, but is generally about 4 to 7 inches (10 to 18 cm) wide.
Sun hats can be made in a variety of materials and styles, including straw hats, conical hats, boonies, and medallions (sun hats). In modern times, sun hats are common around the world, mainly in holiday resorts where there is plenty of direct sunlight, often in tropical countries close to the earth's equator. They are particularly useful in protecting against sunburn and skin cancer of the face and neck caused by UV rays.
A sun hat is an effective piece of sun protection clothing. It shades the face, neck, and shoulders from the sun's harmful ultraviolet (UV) rays. Wearing a sun hat when outdoors in sunny weather can help prevent skin damage, including premature aging, wrinkles, and cancer.
