Why Kangaroo skin ?

Rooskin motorcycle leathers, the Australian contribution to motorcyclists safety, not some "unobtanium" textile fabric made from petrochemicals in a laboratory but grown here and tested by the original owners !!!!

Used by many GP teams for years for the weight saving and of course for the skin saving.

A secret kept by themselves.

We are now making jackets, pants, gloves and suits from kangaroo skin, a few available now. Lightest and toughest leather from the animal that is designed to travel (and crash) at speed .

Most top line race suits have been made from roo for many years and all top end gloves, the feel is exceptional, the abrasion resistance, the best. We have decided to make this available to all, not just the pros

We've made some jackets and trousers for testing and demonstration purposes, A Roo Dominator will be available from stock in all popular sizes soon, other models to order. Any style can be replicated, please email for quote.

Ladies sizes and made to measure too

There is, of course, a price to pay, but for anyone outside Australia please note these are free range animals, not farmed. They are free to go where they want until the day they are culled. This means they do wear the odd battle scar.

 

Wear it with pride

From Wiki

Studies of the morphology of kangaroo leather help explain its particular properties.
The collagen fibre bundles in cattle hide are arranged in a complex weaving pattern. The fibres are often at angles as much as 90 degrees to the skin surface. Cattle hide also contain sweat glands, erector pili muscles and a distinct gradation in elastin levels, concentrated in the upper part of the skin. Kangaroo on the other hand has been shown to have a highly uniform orientation of fibre bundles in parallel with the skin surface. It does not contain sweat glands or erector pili muscles and elastin is evenly distributed throughout the skin thickness [9]. This structural uniformity explains both the greater tensile strength of the whole leather and the greater retention of strength in splits. Bovine skin is much more complex in cross section. Hence in whole section it has many more weak point from which tears can start when placed under tension. In addition when sliced into splits the collagen fibres running at significant angles to the skin surface will be cut. These then become weak points in the structural strength.

 

Kangaroo leather boasts the following performance properties:

High strength
Light weight
Durability
What is so special about kangaroo leather?

The highly organized main fibre bundle structure, which has a secondary fibre mesh in support of the bundles. It is this, combined with the low angle of weave, low fat content and a grain:corium ratio, that provides the superior strength against leathers from such raw materials as cabretta (otherwise known as hair sheep), goat and bovine at similar thickness levels. These particular attributes are explained further below, and are the prime reasons for why K-Leather is the preferred choice for leather products that require lightweight, yet strong, designs.
Angle of Weave
This section refers to the fibre orientation in the corium. The kangaroo fibre structure is aligned almost in parallel to the surface of the leather, and is formed from very long threadlike molecules of proteinous collagen twisted together. This is termed as having a low angle of weave (<30¹), and differs significantly to bovine (cow) products, which typically have weave angles in excess of 60¹, or goat and cabretta leathers, which range between 45¹ and 60¹. The flat fibre structure can be analogous with a rope that has a network of fibres all running in the same direction, and results in exceptional strength.

Low Fat Content
The fat content of the skin structure is often determined by the environment in which the animal lives. The diet of the kangaroo is generally quite poor and this, combined with the extreme heat in which they live, results in virtually no fat within the fibre structure. In comparison a cabretta or goat leather has anywhere between 5% and 8%, while bovine leather is much more variable. Ultimately, fat takes up space in the cross-section of the skin and when it is removed during tanning, “voids” are left, which can cause a reduction in strength per unit thickness.

Grain - Corium Ratio
Most animals have two distinct layers in the cross-section of the skin – the grain and the corium. The majority of the strength comes from the corium, where the fibre bundles are much more dense. However, on certain animals, and in particular bovine substrates, a large amount of the corium is shaved off to gain a lightweight thickness, resulting in dramatically reduced strength characteristics. However, kangaroo skin has a very thin grain layer and it’s thickness can easily be reduced without detriment to the strength of the final leather, owing to the fact that the natural thickness of a kangaroo skin is mainly found to be in the range of 1.0 to 1.2 mm.
