Dry suit
A dry suit is a type of protective clothing worn by scuba divers who are swimming in very cold water, such as in the Arctic ocean or the North Atlantic ocean. A dry suit is similar to a wetsuit, in that it helps to insulate the diver's body from the cold of the ocean. However, a wetsuit lets water to touch the diver's body, but a dry suit is sealed so it does not allow water to touch the diver's body. This means that a dry suit offers more protection from the cold ocean water.
