When it comes to outdoor gear, ropes, and equipment, two materials have long been vying for attention: Dyneema and Nylon. Both have their loyal followings, and for good reason. But which one is better? Is Dyneema’s superior strength and durability worth the extra cost, or does Nylon’s affordability and versatility make it the better choice? In this article, we’ll delve into the world of these two materials, exploring their properties, advantages, and disadvantages to determine which one comes out on top.
The Basics: What are Dyneema and Nylon?
Before we dive into the comparison, it’s essential to understand what these materials are and how they’re made.
Dyneema
Dyneema is an ultra-high molecular weight polyethylene (UHMWPE) fiber produced by the Dutch company, DSM. It’s made through a process called gel spinning, which involves dissolving the polymer in a solvent and then spinning it into fibers. This creates an extremely strong and lightweight material with a high strength-to-weight ratio.
Nylon
Nylon, on the other hand, is a polyamide fiber commonly used in outdoor gear, clothing, and equipment. It’s produced through a process called extrusion, where the nylon polymer is melted and formed into fibers. Nylon is known for its durability, flexibility, and resistance to abrasion and UV light.
Strength and Durability: A Key Comparison
When it comes to strength and durability, Dyneema is the clear winner. Its superior strength-to-weight ratio makes it an ideal material for applications where weight is a critical factor, such as in sailing, climbing, and search and rescue operations. Dyneema’s fibers have a higher tensile strength than Nylon, with a minimum breaking strength of 450 kg (1,000 lbs) compared to Nylon’s 200 kg (440 lbs).
However, Nylon is not without its advantages. While it may not match Dyneema’s strength, it’s more resistant to abrasion and UV light, making it a better choice for applications where the material will be exposed to harsh conditions.
Moisture Resistance: A Key Advantage for Dyneema
One area where Dyneema stands out is in its moisture resistance. Because it’s a hydrophobic material, Dyneema repels water, making it an ideal choice for marine and aquatic applications. This also means that Dyneema is less prone to water absorption, which can lead to weight gain and reduced strength.
Nylon, on the other hand, is more prone to water absorption, which can affect its performance in wet conditions. However, some Nylon products are treated with water-resistant coatings to mitigate this issue.
Weight and Bulk: A Significant Difference
One of the most significant differences between Dyneema and Nylon is their weight and bulk. Dyneema is an extremely lightweight material, with a specific gravity of 0.97 g/cm³ compared to Nylon’s 1.14 g/cm³. This means that Dyneema products are often significantly lighter than their Nylon counterparts.
However, this lightweight nature comes at a cost. Dyneema is often more expensive than Nylon, making it less accessible to budget-conscious consumers.
Cost: A Significant Factor in the Decision
The cost of Dyneema and Nylon products is a significant factor in the decision-making process. Dyneema products are often priced higher due to the material’s superior strength and durability. However, Nylon products can offer similar performance at a lower cost, making them an attractive option for those on a budget.
Knots and Abrasion: Where Nylon Shines
While Dyneema excels in terms of strength and durability, Nylon has some advantages when it comes to knots and abrasion.
Knots
Nylon is more prone to holding knots than Dyneema, making it a better choice for applications where knots are critical, such as in climbing and sailing. This is due to Nylon’s slightly rougher surface texture, which helps to grip the rope and prevent slippage.
Abrasion
As mentioned earlier, Nylon is more resistant to abrasion than Dyneema, making it a better choice for applications where the material will be subject to heavy wear and tear.
Applications: Where Each Material Excels
So, where do each of these materials excel?

- Climbing and ropes courses: Nylon’s ability to hold knots and its resistance to abrasion make it a better choice for climbing and ropes courses.
- Work and industrial applications: Nylon’s durability and affordability make it a popular choice for work and industrial applications, such as in lifting equipment and safety gear.
The Verdict: Is Dyneema Better than Nylon?
So, is Dyneema better than Nylon? The answer lies in the specific application and the priorities of the user. If superior strength, durability, and moisture resistance are critical, Dyneema is the clear winner. However, if affordability, versatility, and resistance to abrasion are more important, Nylon is a better choice.
Ultimately, the decision comes down to balancing the pros and cons of each material and determining which factors are most critical for the specific application.
