A diver's outfit is an essential piece of equipment for any underwater activity. It consists of a wetsuit, fins, mask, and a scuba tank, which is an air supply that allows the diver to stay underwater for extended periods of time. The acronym SCUBA stands for Self-Contained Underwater Breathing Apparatus, which is the most common type of air supply used by divers. A diver's outfit is designed to keep the diver warm and safe while exploring the depths of the ocean.
