Refrigeration suit

A refrigeration suit was a type of clothing used by the Breen. It was supposedly a type of environmental suit to keep a Breen's temperature at a lower level than its surroundings. The Breen theoretically wore them to maintain the cold temperatures on their home planet.

However, in 2375, Weyoun claimed that the Breen homeworld was actually quite mild, thus raising questions over their use of the suits.
