Dyneema fabric is an ultra-high-molecular-weight polyethylene material known for its incredible strength-to-weight ratio, durability, and versatility. But is Dyneema fabric waterproof? The short answer isyes, Dyneema fabric is waterproof. However, there are several factors to consider in order to understand how this material performs in various conditions and applications. In this blog post, we’ll dive into the details of Dyneema’s waterproof properties and how it compares to other materials in the market.

Is Dyneema fabric waterproof?

Waterproof vs. water-resistant

To understand if Dyneema fabric is waterproof, we first need to clarify the difference between waterproof and water-resistant materials. Waterproof materials prevent water from penetrating, thus keeping the contents dry. On the other hand, water-resistant materials can repel water to some extent, but they are not entirely impervious to water penetration.

Dyneema’s waterproof properties

Dyneema fabric is made from ultra-high-molecular-weight polyethylene (UHMWPE) fibers. These fibers are inherently hydrophobic, meaning they repel water. This natural water resistance, combined with the tight weave of the fabric, makes Dyneema waterproof.

Applications of waterproof Dyneema fabric

Dyneema’s waterproof properties make it an ideal material for various applications, such as:

1. Outdoor gear: Tents, tarps, and backpacks made from Dyneema fabric are lightweight, durable, and waterproof, making them perfect for outdoor enthusiasts.

2. Sailing equipment: Dyneema’s high strength and waterproof properties make it a popular choice for sails, ropes, and other marine applications.

3. Protective clothing: Waterproof Dyneema fabric is used in the production of protective clothing for law enforcement, military, and industrial workers who require protection from water as well as abrasion and puncture resistance.

How does Dyneema fabric compare to other waterproof materials?

Dyneema vs. Gore-Tex

Gore-Tex is a popular waterproof material that consists of a thin membrane of expanded polytetrafluoroethylene (ePTFE) laminated to a fabric. While both Dyneema and Gore-Tex are waterproof, they have different attributes:

1. Weight: Dyneema fabric is significantly lighter than Gore-Tex, making it a preferred choice for ultralight gear.

2. Breathability: Gore-Tex is known for its breathability, allowing moisture vapor to pass through while preventing liquid water from entering. Dyneema, however, is not breathable, which may be a disadvantage in some applications.

3. Durability: Dyneema fabric is more resistant to abrasion and punctures compared to Gore-Tex, making it a more durable option for certain uses.

Dyneema vs. Silnylon

Silnylon (silicone-impregnated nylon) is another waterproof material used for outdoor gear. Comparing Dyneema and silnylon, we can note the following differences:

1. Weight: Dyneema fabric is lighter than silnylon, making it a better choice for ultralight gear.

2. Strength: Dyneema is significantly stronger than silnylon, providing added durability and resistance to tearing.

3. Price: Silnylon is generally more affordable than Dyneema fabric, which may be a deciding factor for some consumers.

Caring for Dyneema fabric

To maintain the waterproof properties of Dyneema fabric, it is essential to take proper care of the material. Here are some tips for maintaining Dyneema fabric:

1. Cleaning: Use mild soap and water to clean the fabric. Avoid using harsh chemicals or abrasive materials that may damage the fibers.

2. Drying: Allow the fabric to air dry completely before storing it to prevent the growth of mold and mildew.

3. Repairing: If your Dyneema fabric gets damaged, use Dyneema-specific repair tape or patches to maintain its waterproof properties.


In conclusion,Dyneema fabric is waterproofdue to its hydrophobic UHMWPE fibers and tight weave. Its waterproof properties make it suitable for various applications, including outdoor gear, sailing equipment, and protective clothing. Compared to other waterproof materials like Gore-Tex and silnylon, Dyneema offers advantages such as a lighter weight and superior strength. However, it may not be as breathable as Gore-Tex or as affordable as silnylon. Proper care and maintenance of Dyneema fabric are essential to ensure its longevity and waterproof performance.

Here are ten key facts about Dyneema fabric:

1.Dyneema fabric is waterproofthanks to its hydrophobic UHMWPE fibers.
2. It has an exceptional strength-to-weight ratio, making it a popular choice for lightweight gear.
3. Dyneema fabric is more durable and abrasion-resistant than other waterproof materials.
4. Unlike Gore-Tex, Dyneema is not breathable.
5. Dyneema fabric is generally more expensive than other waterproof materials like silnylon.
6. It is widely used in outdoor gear, sailing equipment, and protective clothing.
7. Dyneema fabric is easy to clean with mild soap and water.
8. Proper drying and storage are essential to prevent mold and mildew growth.
9. Dyneema-specific repair tape or patches can help maintain its waterproof properties.
10. Dyneema fabric’s waterproof properties, combined with its strength and durability, make it a versatile material for various applications.


How long does dyneema fabric last?

Dyneema fabric is known for its exceptional durability and can last for many years, depending on how it is used and cared for. With proper maintenance and storage, dyneema fabric can last for up to 10 years or more.

Does Dyneema absorb water?

No, Dyneema does not absorb water.

How do you care for Dyneema fabric?

Dyneema fabric can be cared for by hand washing in cold water with a mild detergent, and then air drying. Avoid using bleach or fabric softeners, and do not machine dry or iron. Additionally, avoid exposing Dyneema fabric to excessive heat or sunlight, as this can cause damage to the material.

Why is Dyneema so expensive?

Dyneema is a high-performance material that is extremely strong, lightweight, and durable, making it ideal for a wide range of applications, including aerospace, defense, and sports equipment. Its production process involves advanced technology and requires high levels of quality control, which contributes to its high cost. Additionally, its unique properties make it a premium material, commanding a higher price point in the market.

How long does Dyneema fabric last?

Dyneema fabric is known for its exceptional durability and can last for many years depending on usage and maintenance.

How durable is Dyneema fabric?

Dyneema fabric is highly durable and has a high resistance to abrasion, tearing, and punctures. It is considered one of the strongest and most durable materials available for outdoor gear and equipment.
