Discovered 50 years ago, aramid fiber is a very strong, light and durable synthetic fiber. Marketed by the American company Dupont de Nemours with the name "Kevlar", this material quickly became a standard in motorcycle equipment due to its extreme resistance.

But what exactly is Kevlar

Poly-paraphenylene terephthalamide (PPD-T) is a thermoplastic polymer better known as "Kevlar". It is a material formed by combining para phenylenediamine and terephthaloyl chloride. This results in aromatic polyamide (aramid) yarn. Kevlar is a very light fiber and 20 times stronger than steel.

So what about the protection of the motorcyclist?

Kevlar is primarily useful for preventing abrasion. Abrasion is a major danger for motorcyclists during a crash because unlike the hands and head - which require mandatory and approved equipment - there is no requirement for protective clothing for the body. With the growing interest in motorcycling, an increasing number of motorcyclists wear simple clothing without any real protection against abrasion or burns when the motorcyclist's skin rubs against the asphalt.

This can lead to extremely severe level 3 burns, resulting in complete destruction of the dermis and epidermis. Skin grafting is then the only alternative as healing becomes impossible.


In order to protect oneself effectively, it is therefore necessary to find an anti-abrasion garment that combines lightness, resistance to tearing as well as to breaking, while keeping a biker spirit. You can find on the market anti-abrasion clothing with complementary accessories for maximum safety, such as protections for shoulders, back - dorsal -, elbows and knees.

The protections of such equipment have not been placed at random. If their use in an integral way is often privileged on circuit, they can be homologated and are extremely important in case of fall or shock in a daily context.

How about the traditional leather jacket?

We know that some bikers have an unconditional love for leather! In addition to giving a very appreciated atypical look to the one who wears it, leather is a very solid material which offers an optimal protection.

For years now, everyone has known the great resistance of leather to abrasion. This is one of the main reasons why it is so widely used, especially in competition. 


Also, in addition to these essential qualities, modern leather jackets offer new properties such as thermal linings or numerous options for pockets.

Kevlar might be a good alternative to traditional leather?

Indeed. Although modern leather jackets have become lighter and more comfortable thanks to the innovations of the new removable linings, they are still a step below textile jackets when it comes to bad weather. In fact, today's motorcycle jackets have become very advanced from a technical point of view, especially when it comes to textiles and their waterproofing.

Most of the time, textile jackets are lightweight and let sweat evaporate while being waterproof, so jackets equipped with a waterproof and breathable membrane can be worn in summer while protecting from rain. This makes them an excellent alternative to leather when conditions permit. 

Be aware that the more you go upmarket, the more your textile jacket will be equipped to resist in case of an accident.

Then Kevlar is the perfect material for my motorcycle jacket!

It is true that thanks to the exceptional resistance that a Kevlar lining confers to a textile jacket while preserving the waterproof and breathable properties of the latter, choosing this material seems to be a most recommendable choice. 

A Kevlar-lined textile motorcycle jacket is the perfect alternative, especially for keeping cool, comfortable and optimally protected when temperatures rise and become unsuitable for a leather jacket.
