Fun fur is a synthetic fabric which looks and feels like the fur that many types of animals have to cover their skin. It can be used to make most any kind of clothing, most commonly pants. Fun fur is probably most common among ravers, especially those of the candykid variety. However, sightings of office workers, senior citizens, and even politicians wearing fun fur have been noted.
It is one of the few clothing materials for pants that is both very comfortable and very warm at the same time. Fun fur pants are also commonly called 'fuzzy pants'. As you would expect, fun fur comes in many different colours, and also a few different textures.
