A raincoat is a waterproof outer garment designed to protect the wearer from rain. Typically made from synthetic materials such as nylon or polyester, raincoats often feature a hood to shield the head and sometimes include additional features like pockets, adjustable cuffs, and ventilation flaps to enhance comfort and functionality. They come in various styles, lengths, and colors to suit different preferences and climates, providing practical protection against inclement weather while allowing the wearer to remain dry and comfortable outdoors.
