Kangaroo Skin is a strong light skin that comes from kangaroo skin.
Kangaroos are harvested. Both the meat and the skin are sold. Although most species of macropods are protected from hunting by law, a small number of large species that exist in large numbers can be hunted by commercial hunters. This policy has been criticized by some wildlife activists.

This leather is used in various kinds of shoes. The unique structure of kangaroo skin allows it to be cut into a very thin substance (skin thickness) but retains strength.
Kangaroo skin is also popular in the manufacture of motorcycle leather and is used to make a wide range of other applications such as car coatings, military boots, soccer shoes or soccer shoes and fashion accessories.
The kangaroo skin is the material of choice for the whip maker because the strips can be cut thinly to keep the whip flexible, without sacrificing endurance.

Properties
Studies conducted by the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO) confirm that kangaroos are one of the strongest skins of similar substances available.
Similarly, when broken down into thinner substances, kangaroos retain more of the original tensile strength of the skin that is not grafted than the calf. When it is split into 20% of the original thickness the kangaroos retain between 30 and 60% of the tensile strength of unsplit hide. Calves are split into 20% of the original thickness, on the other hand, retain only 1-4% of the original strength.
The skin of kangaroos is lighter and stronger than cow or goat skin. It has 10 times the tensile strength of cow skin and is 50% stronger than goat skin.
The study of kangaroo skin morphology helps to explain its particular nature.
Collagen fiber fibers in cowhide are arranged in intricate weaving patterns. The fibers are often at an angle of 90 degrees to the surface of the skin. Cow hide also contains sweat glands, pili erector muscles and different gradations in elastin levels, concentrated in the upper part of the skin. Kangaroos hiding on the other hand have been shown to have a very uniform orientation of fiber bundles in parallel with the surface of the skin. Does not contain sweat glands or pili muscles erectors and elastin distributed evenly throughout the skin thickness. This structural uniformity explains the greater tensile strength of the whole skin and the greater retention of forces in division. Cowhide is much more complex in transverse sections. Therefore in all parts there are many weak points that can cause the tears to start under pressure. Additionally when sliced ​​into a split collagen fiber running at a significant angle to the surface the skin will be cut. This then becomes a weak point in the structural strength.
Environmental aspects
The Australian kangaroo industry produces a variety of meat and skin products from animals harvested from the wild under strictly controlled Government Management Plan. This ensures a sustainable and humane harvest. A wide cross section of Australian ecologists supports the kangaroo industry as sustainable and environmentally sound. Many think kangaroos, originally from Australia, are a more environmentally-friendly choice of livestock than introduced cattle and sheep. The two most important aspects of better kangaroo ecological suitability of European farm animals relate to their adaptation to Australia's aridity. Kangaroos have small chest developments requiring less water to breathe than placental mammals, which usually have to expand the diaphragm. This means they lose more moisture in respiration. Kangaroos only make small pants while not moving and move extending and contracting their lungs effectively using their leg muscles. The stomach jumps up and down, contracts and extends into the lungs. Also, kangaroo claws are softer and do not solidify the ground like a herd of cows and sheep. In contrast, the leaf is a very small leaf-shaped piece on the surface of dry clay, which allows the original seed grass to be carried by the wind. The bowl shape concentrates every moisture that falls into it into a wet point that grass seeds can use to germinate. Thus, kangaroos spend water on the table at a slower rate than cattle or sheep and would even be feasible due to the absence of drill water at all. Ecological arguments for kangaroos replacing sheep and cattle as land animals are interesting, although they must oppose the objection to the lack of domestication and the rate of kangaroo breeding. Kangaroos are eaten in most states.
