A raincoat is a waterproof or water-resistant outer garment designed to protect the wearer from rain. Typically made from materials like polyester or nylon, raincoats often feature a hood and adjustable cuffs to keep water out. They come in various styles and colors, making them suitable for both casual and formal occasions. Raincoats are essential for staying dry during wet weather. Many are lightweight and can be easily folded for storage, making them convenient to carry. Some raincoats also include reflective elements for safety, especially for those walking or biking in low-light conditions.
