Lightweight rainwear is a type of clothing designed to protect the wearer from rain and other elements. The most common form of lightweight rainwear is the PONCHO, which is a single piece of fabric with a hole in the middle for the head and armholes at the sides. Ponchos are usually made from waterproof materials such as nylon or polyester, and they are lightweight and easy to carry. They can be worn over other clothing to provide extra protection from the rain.
