Chamois Skin ( ) is a porous skin type, traditionally chamois leather (Rupicapra rupicapra), a kind of European mountain goat but today is made almost exclusively of split meat from sheepskin. This skin is favored because of its soft, non-abrasive composition and its absorption properties. It has various uses:
- Gloves in the 19th to the first half of the 20th century
- Leather jackets, small bags, and pockets
- Wrap up fabrics for gems or shoes
- Filter the fuel
- Safe automotive drying materials on acrylic paints, lacquer, enamel, and polyurethane and clear-coats
- General household cleaning
- Orthopedics and other medical uses
Imitation chamois leather is made using other leather (such as domestic goat, or pig), and synthetic chamois leather is usually made of polyvinyl alcohol or viscose non-woven rayon.

The British Standard BS 6715: 1991 defines the chamois skin as:
"Leather made of sheepskin or sheepskin, or of sheepskin or sheepskin from which the grain (top split) has been removed by frizing, and tanned by a process involving the oxidation of sea oil in the skin."

United States
In the United States, the term chamois is unqualified limited to the distribution of sheep or sheepskin tanned only with oil (US Federal Standard CS99-1970).
Chamois skin is often faked with goatskin or pigs, whose practice is a particular profession called by the chamoiser chamoiser chamoiser .
History
The term chamois as used to refer to specially prepared skin originated sometime before 1709, refers to skins prepared from animals such as goats, in particular the European Antelope - commonly called "chamois" - - and exclusively used by the glovemaking industry of southwest France. It was found that when tanned in local fish oil near Biarritz, the result was an unprecedented ingredient. This leather is made into a soft white glove designed for pedestrian carriages, which is responsible for the care and polishing of the carriages. The industrial use was then transferred to a "horse-carriage" driver discovered in the early 1900s. The popularity of chamois leather greatly increases with the advent of mass-produced windshields of cars, which need to be washed frequently for visibility purposes, but it is uncomfortable and time consuming to dry through alternative means.
Properties
Original chamois skin has almost no abrasive properties, and can be used as a highly absorbent drying material for any car surface. This has made it a popular product for car cleaning and drying.
The elasticity of the skin pores, which is very close, allows for use in micro-filtration. The water absorbency makes it great for other uses, such as cycling shorts (though most modern cycling shorts now use "chamois" synthetic leather). It is also used in purifying the mercury, which is done by passing it through the pores of the skin.
When immersed in clean petrol, chamois will not allow water to pass through its surface fibers. This property is used to filter fuel that has been stored in drums susceptible to water entry, or from other questionable sources. The technique is to provide a large mouthed mouthpiece with a wide outlet surface supporting the base of woven wire, or metal plate with a hole grating. The bottom of the funnel is tapered to fit the container or tank-filler hole.
Suitable sized chamois skin is immersed in clean fuel and placed on top of the grid in the funnel and raised side, forming a bowl, to prevent leakage through the skin. The fuel can then be pumped to the top of the funnel by a fuel dispenser and keep an eye on the signs of water accumulation. This process can be stopped to lift the assembly from the trapped tank and water is removed so that the work can proceed. Chamois leather is used so as a fuel filter by sailors, automated details - and airplane refuellers, especially from past ages when aircraft are flown to very remote areas.
Usage
Widely used for drying and scrubbing vehicles, such as cars and vans, after washing.
Small pieces of chamois leather (often called "chamois fabric") are usually used as a mixing tool by the artist drawing with charcoal. The skin combines charcoal softer and cleaner than the artist's fingers, which can leave stains. The chamois is also used to lighten the image (or part of it) by removing some charcoal in a more subtle and nuanced way than most erasers can. Charcoal can be washed from the skin using soap and water.
Chamois leather is used around professional film and video camera viewfinders, as it provides comfort and absorbs the sweat from the camera operators who spend a long time with their eyes planted in the viewfinder.
Divers use a towel made of chamois leather to dry themselves in between jumps, as they can be quickly dried by squeezing them.
