A sun hat is a type of headwear designed to protect the face, neck, and ears from the sun's harmful rays. Typically made from lightweight materials like cotton or straw, sun hats often feature wide brims that provide shade. They are popular for outdoor activities such as gardening, hiking, and beach outings. Sun hats come in various styles, including wide-brimmed hats, bucket hats, and visors. Many are designed with ventilation features to keep the wearer cool. Wearing a sun hat is an effective way to reduce the risk of sunburn and long-term skin damage while enjoying time outdoors.
