open air

Without roof overhead

Open air refers to the outdoors, especially as distinguished from enclosed spaces: We ate lunch in the open air.

As a modifier (often hyphenated), it describes things happening outside: an open-air market, an open-air concert.

The phrase emphasizes exposure to sky and atmosphere rather than walls and ceiling.
