8 Real Benefits of Kevlar Motorcycle Jeans from a Rider

Kevlar motorcycle jeans do provide meaningful protection, offering far greater abrasion resistance than ordinary denim while keeping the look and comfort of regular jeans.

When you first come across the term ‘Kevlar motorcycle jeans,’ it’s natural to assume it refers to a specific brand of jeans. And you’re not alone! It’s a common misconception that I’m here to clarify. In reality, Kevlar motorcycle jeans are made of denim, which is a cotton or cotton-blend twill textile, the same material used in your regular jeans that we all own and love. Their protective performance comes from reinforcement with Kevlar panels or a Kevlar lining.

Kevlar is a heat-resistant para-aramid, a strong synthetic fiber closely related to other aramids like Nomex, Twaron, Technora, Heracron, and Alkex. Back in 1965, Stephanie Kwolek’s pioneering work at DuPont led to the development of this groundbreaking material, making it her most notable contribution to polymer research.

Initially, Kevlar found commercial use as a substitute for steel in radial tires during the early 1970s. Since then, its versatility has led to its integration into various applications, including motorcycle jeans and some motorcycle helmets, exemplified by HJC’s PIM (Premium Integrated Matrix) shell as showcased in their DOT and ECE HJC RPHA 12 approved helmet.

This brings us to the question at hand: how good are Kevlar motorcycle jeans?

How Kevlar Motorcycle Jeans Protect You

I can practically hear the gears turning in your head, wondering, ‘Do Kevlar motorcycle jeans really work?‘ Yes, Kevlar motorcycle jeans do work, and I first became familiar with the ingenuity upon their introduction in 1997 (yes, they’ve stood the test of time and earned their rightful place!). You see, I’m no stranger to the motorcycle world; I’ve been riding and involved in designing gear for more than 50 years.

But since moving away from sport bikes (though I do indulge in the occasional adrenaline rush at the California Superbike School or Sandy Hook Speedway, because, hey, one can never truly outgrow the thrill of racing), I’ve since expanded my horizons to embrace the thrill of adventure, street, custom, naked, and cruiser machines. Of course, my choice of trousers has evolved accordingly, and more often than not, you’ll find me rocking a pair of motorcycle Kevlar jeans. Why? Allow me to share my reasons.

To ensure a clear understanding of the benefits of Kevlar motorcycle jeans, I will explain the advantages of Kevlar itself and how these benefits directly apply to its application in motorcycle jeans. This will provide a comprehensive understanding of why Kevlar is such a valuable material in the context of motorcycle apparel.

1. Stronger Than Steel

Allow me to clarify right from the outset. There are three grades of Kevlar:

1. Kevlar: This is the standard form of Kevlar, which you and I will be addressing in this post, and it’s commonly used as reinforcement in motorcycle jeans. It’s also prevalent in tires and rubber mechanical goods. The tensile strength of standard Kevlar fibers typically ranges around 3.6 GPa (gigapascals) or 525,000 pounds per square inch (psi). 
2. Kevlar 29: Kevlar 29 offers higher strength than standard Kevlar due to its tougher yarns. It finds industrial applications in brake linings, asbestos replacement, cables, and body armor. Kevlar 29 has a tensile strength of approximately 3.6 to 4.1 GPa or 525,000 to 595,000 psi.
3. Kevlar 49: Among all the aramids, Kevlar 49 exhibits the highest tensile strength. It’s primarily used to reinforce plastics in various applications, including bicycles, boat hulls, and airplanes. With a tensile strength ranging from approximately 3.6 to 4.8 GPa or 522,000 to 696,000 psi, Kevlar 49 surpasses both standard Kevlar and Kevlar 29 due to its tougher yarns.

Note: Sunlight’s ultraviolet light degrades and decomposes Kevlar, rendering it seldom used outdoors without protection against sunlight.

The truth is, in the event of a fall, the denim in motorcycle Kevlar jeans will wear away upon contact with the road. That’s precisely why I strongly advise against riding in your regular jeans, or if you’d like to hear about a harrowing firsthand experience, I invite you to read about my unfortunate mishap. And when this happens (because it’s not a matter of “if” but “when,” given the inherent characteristics of denim such as shorter cotton fibers and a diagonal twill weave pattern) the Kevlar panels or lining will protect you from significant injuries caused by abrasion.

You see, Kevlar’s strength surpasses that of steel by 10 times on an equal weight basis, and this can be explained through the concept of tensile strength. Tensile strength is the maximum amount of tensile stress a material can withstand before breaking. It’s typically measured in units of force per unit area (such as MPa or psi). FOR A MORE SPECIFIC EXPLANATION ON THIS, PLEASE REFER TO THE SECOND POINT. Take your time. I’ll give you two minutes as you prepare for the scientific ride of your life.

And now that you have, allow me to calculate the strength-to-weight ratio for both materials to provide you with a clearer understanding.

I will use the formula:

Strength-to-Weight Ratio = Tensile Strength / Density

• For Kevlar

Tensile Strength of Kevlar: Approximately 3.62 gigapascals (GPa) or 525,000 pounds per square inch (psi).

Density of Kevlar: Roughly 1.44 grams per cubic centimeter (g/cm³).

Now, let’s calculate the strength-to-weight ratio for Kevlar using the formula:

Strength-to-Weight Ratio (Kevlar) = Tensile Strength of Kevlar / Density of Kevlar

Strength-to-Weight Ratio (Kevlar) = (3.62 GPa) / (1.44 g/cm³)

Calculating this ratio:

Strength-to-Weight Ratio (Kevlar) ≈ 2.51 GPa·cm³/g

This means that Kevlar has a strength-to-weight ratio of approximately 2.51 gigapascals per cubic centimeter per gram (GPa·cm³/g). The value represents the material’s strength in relation to its weight, indicating the impressive strength Kevlar possesses for its density.

• For Steel

Tensile Strength of Steel: Varies depending on the type, but typically around 370 to 1,000 megapascals (MPa) or 53,600 to 145,000 psi.

Density of Steel: Approximately 7.8 grams per cubic centimeter (g/cm³).

Now, let’s calculate the Strength-to-Weight Ratio for steel:

Strength-to-Weight Ratio (Steel) = Tensile Strength of Steel / Density of Steel

Strength-to-Weight Ratio (Steel) = (370-1000 MPa) / (7.8 g/cm³)

Calculating this ratio:

Strength-to-Weight Ratio (Steel) ≈ 128.21 MPa·cm³/g

This means that the maximum strength-to-weight ratio for steel is approximately 128.21 megapascals per cubic centimeter per gram (MPa·cm³/g). The value represents the maximum strength of steel relative to its weight.

By comparing these figures, we can see that Kevlar exhibits an exceptional strength-to-weight ratio compared to steel. Kevlar’s high tensile strength, combined with its lower density, results in a significantly higher ratio. This means that on an equal weight basis, Kevlar possesses far greater strength than steel, making it an outstanding material choice for application in motorcycle jeans, which demand strength and durability while minimizing weight.

It’s important to note that several factors, including its molecular structure and bonding, influence the strength of a material. In the case of Kevlar, its exceptional strength can be attributed to the following:

• Molecular Alignment: Kevlar fibers have a highly aligned molecular structure, with polymer chains parallel to each other. This alignment contributes to the efficient transfer of load-bearing forces along the fiber, enhancing its overall strength.
• Bonding and Interactions: Kevlar’s chemical structure includes strong covalent bonds between atoms, which provide strength and stability. Additionally, intermolecular forces, such as van der Waals forces, contribute to the material’s cohesive strength and resistance to deformation.

In essence, Kevlar’s exceptional strength-to-weight ratio, combined with its molecular alignment and bonding, contributes to its superior strength even when confronted with the unforgiving roughness of the tarmac.

2. High Tensile Strength

Kevlar’s high tensile strength allows it to withstand greater forces without tearing or ripping, providing added durability and protection to Kevlar motorcycle jeans. 

Normally, you can determine the tensile strength through tensile testing, where you subject a sample of the material to an increasing amount of force until it fractures. In this regard, Kevlar performs exemplarily, with a tensile strength measure of about 3.62 gigapascals (GPa), or 525,000 pounds per square inch (psi), whereas nylon has a tensile strength of about 0.75 gigapascals (GPa). I hope you can see the huge difference!

To arrive at these figures, you divide the maximum force (F) applied to Kevlar by the original cross-sectional area (A) in order to calculate the tensile stress (σ).

The formula for tensile stress is:

Tensile Stress = Force / Cross-Sectional Area (σ = F / A)

The cross-sectional area can be determined using the formula:

A = π * r^2

where π is a mathematical constant approximately equal to 3.14159, and r is the radius of the specimen.

Let’s assume we have a force of 5,000 Newtons (N) applied to a Kevlar sample with a cross-sectional area of 0.05 square meters (m²). We can calculate the tensile stress as follows:

Tensile Stress = 5,000 N / 0.05 m²

Performing the calculation:

Tensile Stress = 100,000 Pascal (Pa)

So, in this example, the tensile stress of the Kevlar sample would be 100,000 Pascal (Pa). The high tensile strength means that it can resist significant forces without tearing or ripping.

Such an evaluation is vital for assessing its performance, ensuring safety, and guiding the design and production of Kevlar motorcycle jeans, where the material needs to withstand the stresses and strains experienced during motorcycle riding. The high tensile strength of Kevlar enhances the durability and protection provided by the jeans, making them a reliable choice for riders seeking added safety.

3. Ballistic Resistant 

Ballistic resistance refers to a material’s ability to withstand the impact and penetration of projectiles, such as bullets or shrapnel. And Kevlar’s exceptional ballistic resistance (which I will illustrate below) translates to superior protection against impacts. 

While motorcycle accidents may not involve bullets or shrapnel, the same principles apply to the potential impact of debris, sharp objects, or other hazards encountered on the road. Kevlar’s ballistic resistance is primarily attributed to its high tensile strength (3.62 GPa, or 525,000 psi) and energy-absorbing properties, including impact resistance, flexibility and resilience, and fracture resistance. 

When a projectile strikes the Kevlar fabric, the strong bonds between the polymer chains distribute the impact energy throughout the material, effectively absorbing and dissipating the force. This prevents the projectile from penetrating the fabric and reaching the lower half of your body (from the waist to the ankles), mitigating the risk of injury.

Now, let’s move on to the illustration part. Calculating the ballistic resistance of Kevlar involves complex and specialized testing procedures. Fortunately, my involvement in the research and design of Kevlar motorcycle jeans in the current market has provided me with valuable insights to share. The most common method used is the National Institute of Justice (NIJ) Standard-0101.06, which provides standardized testing protocols for body armor materials, including Kevlar.

The testing typically involves firing specific ammunition types at various velocities and recording the penetration depth or backface signature (the deformation of the material on the opposite side of impact) on the material being tested.

Here’s my simplified overview of the process:

• Test Setup: A sample of Kevlar material, often in the form of a panel or multiple layers, is prepared for testing. This sample is typically placed in a controlled testing environment.
• Projectile Selection: The type and caliber of the projectile(s) to be used are determined based on the specific testing standards and requirements.
• Velocity Determination: The ammunition is fired at the Kevlar sample at a range of predetermined velocities. The velocity of each shot is carefully measured and recorded.
• Penetration Measurement: The depth of penetration into the Kevlar sample is measured and recorded for each shot. This determines the material’s ability to resist penetration by the projectile.
• Backface Signature Measurement: The deformation or indentation on the opposite side of the material (the “backface signature”) resulting from the impact is measured and recorded. This measurement assesses the material’s ability to distribute and absorb the impact energy.
• Analysis and Certification: The collected data is analyzed, and the performance of the Kevlar material is evaluated against the specific ballistic resistance standards. If the material meets the required criteria for a given threat level, it can be certified for use in body armor applications.

Kevlar’s ballistic resistance grading levels are as follows:

• Level IIA: Designed to provide protection against 9mm and .40 S&W ammunition, with velocities typically up to 1,235 fps.
• Level II: Offers protection against 9mm and .357 Magnum ammunition, with velocities generally up to 1,430 fps.
• Level IIIA: Provides protection against a wider range of threats, including 9mm, .357 SIG, and .44 Magnum ammunition, with velocities typically up to 1,450 fps.
• Level III: Designed to stop rifle rounds such as 7.62x51mm NATO and 5.56x45mm NATO (commonly known as .308 Winchester and .223 Remington, respectively), with velocities generally up to 2,780 fps.
• Level IV: Offers the highest level of protection, designed to stop armor-piercing rifle rounds like .30-06 M2 AP and .338 Lapua Magnum, with velocities often up to 2,880 fps.

To ensure clarity, allow me to briefly clarify the units of measure mentioned in the preceding response:

• FPS: FPS stands for “feet per second.” It’s a unit used to measure the velocity or speed of a projectile. In the context of ballistic protection, FPS indicates the speed at which a bullet or round is traveling when it impacts the protective material.
• SIG: In the context of Level IIIA ballistic protection, “.357 SIG” refers to a specific type of ammunition. It’s a bottlenecked cartridge developed by SIG Sauer, a firearms manufacturer. It’s designed to provide high velocity and performance.
• mm: “mm” stands for millimeter, which is a metric unit of length. In the context of ballistic protection, it’s used to indicate the caliber of ammunition.
• S&W: S&W stands for Smith & Wesson, a prominent firearms manufacturer. In the context of ballistic protection, “.40 S&W” refers to a specific type of ammunition, .40 Smith & Wesson, commonly used in handguns.

It’s important to note that the actual ballistic resistance of Kevlar can vary depending on several factors, such as the specific construction, layering, and design of the material, as well as the testing standards and requirements being used.

4. Cut and Puncture Resistant

Kevlar is also known for its impressive cut and puncture resistance. This property is a result of its high tensile strength and toughness.

When a sharp object attempts to cut or puncture Kevlar, the material’s molecular alignment and bonding come into play. The aligned polymer chains and strong intermolecular forces prevent the sharp object from easily splitting or penetrating the material. Instead, the forces are distributed along the fibers, minimizing the risk of cuts or punctures.

I will use several formulas and calculations to explain Kevlar’s performance in regards to cut and puncture resistance.

Cut Resistance

The cut resistance of Kevlar is assessed using standardized test methods such as: ASTM F1790 (U.S.), EN 388 (Europe), and ISO 13997 (International).

• ASTM F1790: This test method, developed by the American Society for Testing and Materials (ASTM), is titled “Standard Test Method for Measuring Cut Resistance of Materials Used in Protective Clothing.” It’s widely used to determine the cut resistance of various materials, including textiles and fabrics. The test involves using a circular blade or straight edge blade to cut through the material under controlled conditions. 
• ISO 13997: This international standard, developed by the International Organization for Standardization (ISO), is titled “Protective clothing – Mechanical properties – Determination of resistance to cutting by sharp objects.” It provides a similar approach to ASTM F1790 but utilizes a different method for determining cut resistance. ISO 13997 involves using a knife blade or razor blade to cut through the material under specified conditions.
• EN 388: This test standard, established by the European Committee for Standardization (CEN), is titled “Protective Gloves against Mechanical Risks.” While primarily focused on gloves, it also provides a framework for evaluating the mechanical properties of other protective clothing materials, including cut resistance. The EN 388 standard assesses various performance parameters, including abrasion resistance, cut resistance, tear resistance, and puncture resistance. 

When a sample of Kevlar fabric is subjected to a circular blade or straight edge blade in ASTM F1790 or a knife blade or razor blade in ISO 13997 test method, the force required to cut through the material is measured using load cells such as strain gauge load cells, piezoelectric load cells, or hydraulic load cells. These load cells are integrated into the testing equipment such as STM 611 SATRA and Testometric.

Load cells convert mechanical force into an electrical signal that can be quantified and recorded, and the results are expressed in terms of a cut resistance level. This level is typically categorized from Level 1 to Level 5, with higher levels indicating greater resistance to cuts. The tests are conducted using the same testing equipment and procedures to ensure consistent and reliable evaluations of the material’s cut resistance.

Puncture Resistance

Puncture resistance refers to Kevlar’s ability to withstand the penetration of sharp objects, such as nails or thorns, that you may encounter on the road while riding or during adventurous off-road excursions.

To measure puncture resistance, you need a specific testing equipment like the Puncture Probe and Load Cell. The force is applied to the material using a pointed or sharp object. The maximum force the material can withstand before puncturing is determined, and the results are reported in terms of a puncture resistance level. 

Similar to cut resistance, puncture resistance levels are often categorized from Level 1 to Level 5, with higher levels representing higher resistance to punctures. Standardized test methods are used to ensure consistent and accurate measurements of the material’s puncture resistance.

The two commonly used methods are:

• ASTM F1342: This test method, developed by the American Society for Testing and Materials (ASTM), is titled “Standard Test Method for Protective Clothing Material Resistance to Puncture.” It provides guidelines for evaluating the puncture resistance of protective clothing materials, including woven and non-woven fabrics. The test involves puncturing the material with a specifically sized and shaped puncture probe under controlled conditions. The force required to penetrate the material is measured, and the results are reported as a puncture resistance value.
• EN 388: The EN 388 standard, issued by the European Committee for Standardization (CEN), is titled “Protective Gloves Against Mechanical Risks.” While this standard primarily focuses on glove testing, it includes a test for puncture resistance. The test involves using a standardized puncture probe to penetrate the material, and the force required to puncture the material is measured. The results are reported as a puncture resistance rating based on a scale from 1 to 4, with higher ratings indicating greater puncture resistance.

Material Thickness

The thickness of the Kevlar material ranges between 0.27 and 0.19 inches, and this thickness range significantly influences its cut and puncture resistance. In general, thicker materials tend to offer greater resistance to cuts and punctures compared to thinner ones. This is because a thicker material provides more layers for the cutting or puncturing force to pass through, increasing the overall resistance. 

However, it’s important to consider that other factors, such as the specific construction and weave pattern of the Kevlar fabric, can also influence its protective properties. These factors affect the distribution and alignment of the Kevlar fibers, which impact the material’s ability to resist cuts and punctures.

Composite Materials

Kevlar is often used in composite structures where it is combined with other materials, such as resins or metals, to enhance overall strength and resistance. The performance of composite materials can be evaluated using various formulas, calculations, and theories. 

One commonly employed method is laminate theory. Laminate theory involves analyzing the mechanical behavior of layered structures by considering factors such as layer thickness, orientation, and material properties.

By applying laminate theory, engineers can predict and optimize the composite material’s cut and puncture resistance based on the properties and arrangement of the constituent materials within the composite structure. This allows for designing composite materials with enhanced protective capabilities.

5. Heat and Abrasion Resistant

Kevlar exhibits excellent heat resistance and abrasion resistance due to its chemical structure and inherent properties.

The high melting point of Kevlar, influenced by its strong covalent bonds, enables it to withstand elevated temperatures without melting during slides or degrading over time, thereby increasing the lifespan of your motorcycle jeans.

Moreover, the material’s tightly aligned and bonded polymer chains, along with its intermolecular forces, contribute to its resistance against deformation and abrasion. These properties make Kevlar highly durable and capable of enduring wear and tear in challenging environments.

Determining the heat and abrasion resistance involves considering various factors and testing methods. Here’s an overview of how these properties are typically evaluated:

Heat Resistance

The heat resistance of Kevlar is often determined by conducting thermal stability tests. Here are a few commonly employed methods:

• Thermogravimetric Analysis (TGA): TGA is a widely used technique to assess the thermal stability and decomposition behavior of materials. In TGA, a small sample of Kevlar is heated at a controlled rate under an inert atmosphere (such as nitrogen) while its weight is continuously measured. The test measures the weight loss of the material as a function of temperature, allowing the determination of its thermal stability and the temperature range at which significant decomposition or degradation occurs.
• Differential Scanning Calorimetry (DSC): DSC is another commonly used technique to evaluate the heat resistance of materials. It measures the heat flow (enthalpy) associated with endothermic or exothermic processes occurring in the sample as it is subjected to controlled heating. By analyzing the resulting thermal curves, you can determine the glass transition temperature, melting temperature, and heat capacity of Kevlar. These parameters provide insights into the material’s thermal stability and its ability to withstand heat.
• Thermal Mechanical Analysis (TMA): TMA involves applying controlled mechanical forces to a sample of Kevlar while subjecting it to controlled heating. The technique measures the dimensional changes (expansion, contraction, or softening) of the material as a function of temperature. By monitoring these changes, TMA can provide information about the thermal stability, thermal expansion, and softening behavior of Kevlar under specific conditions.

All the three tests involve subjecting Kevlar samples to elevated temperatures for a specified duration and monitoring any changes in the material’s properties. The exact testing procedure and conditions may vary depending on the specific requirements and standards relevant to the application.

Changes in properties such as tensile strength, elongation, or melting temperature will be measured to assess the material’s heat resistance.

Abrasion Resistance

Abrasion resistance refers to the ability of Kevlar to withstand rubbing or frictional forces without significant damage or wear. Abrasion resistance testing typically involves subjecting Kevlar samples to abrasive materials or surfaces under controlled conditions. The material’s resistance to abrasion can be assessed by measuring weight loss, surface damage, or changes in appearance before and after the test. 

You can use various testing methods and equipment, such as Taber abrasion testers or Martindale abrasion testers, depending on the specific requirements and standards.

Whoa, okay, that was a comprehensive explanation of the advantages of Kevlar in enhancing motorcycle jeans. It’s all backed by science, calculations and formulas. But let’s not stop there! What are the other advantages of Kevlar motorcycle jeans?

6. Properly Tested and Certified

Starting from April 21, 2018, there has been a legal requirement for all motorcycle gear, including motorcycle jeans, to obtain certification as Personal Protective Equipment (PPE). This certification is indicated by a label inside the gear, which reflects its rating based on the CE testing standards EN 13595 or EN 17092. These standards classify the gear into five levels: A, AA, AAA, Class B, and Class C.

Let’s explore what each of these levels entails in terms of protective performance and capabilities:

• Level AAA: This is the highest level of certification and represents the highest level of protective performance. Gear rated as Level A provides the highest abrasion resistance, impact protection, and seam strength. It is designed for professional riders or those seeking maximum protection during high-speed riding.
• Level AA: Gear certified as Level AA offers excellent protection, just slightly below Level AAA. It provides high abrasion resistance, impact protection, and seam strength, making it suitable for a wide range of riders, including those who engage in adventure touring.
• Level A: Level AAA certification signifies a high level of protection. It offers substantial abrasion resistance, impact protection, and seam strength. Gear with this rating is ideal for riders who prioritize safety and require reliable protection for urban riding.
• Class B: Class B certification represents a good level of protection, and somewhat similar to A, but doesn’t consider impact protection. Gear with this rating offers a moderate level of abrasion resistance and seam strength. It is suitable for riders who seek a balance between protection and comfort, such as urban or casual riders.
• Class C: Class C certification indicates a basic level of protection. Gear with this rating provides a lower level of abrasion resistance, impact protection, and seam strength. It is suitable for riders who prioritize off-road riding but still desire some level of protection.

The rating system of AAA, AA, A, Class B, and Class C simply indicates that your Kevlar motorcycle jeans have undergone thorough testing for abrasion and tear resistance, as well as seam strength, in compliance with current legislation. The EN 17092 certification ensures that the jeans provide optimal safety in the event of an accident. 

To ensure you are investing in a product that meets higher safety standards and has a verified test certificate, the simplest way is to look for the logo. By doing so, you can have greater confidence that you are making a wise investment and prioritizing your safety.

7. Combine Style and Safety

Kevlar motorcycle jeans offer a unique advantage by combining a casual denim look with enhanced safety features, allowing you to effortlessly incorporate them into your everyday attire while prioritizing your protection on the road. These jeans strike a perfect balance between style and functionality, ensuring both comfort and safety during your motorcycle rides. 

But it’s important to be aware that in hot weather conditions, the Kevlar material’s limited ventilation may result in increased heat retention. Consequently, they may not be the most ideal choice for prolonged use in such conditions.

8. Added Knee and Hip Protection

In addition to the Kevlar lining, it’s essential to ensure proper coverage in high impact areas such as knees, butt, and hips to protect against abrasion in the event of a fall. High-quality Kevlar motorcycle jeans go a step further by incorporating armor, particularly knee and hip armor, for enhanced protection. AAA-rated lined jeans also take it up a notch and are highly likely to provide even greater abrasion resistance compared to their single-layer counterparts.

Now, I understand this may sound like a bold claim, one that challenges what you may have seen in certain articles online and YouTube videos. But in the quest for accurate and reliable information, whom should you trust?
