The Most Important Guide to Backpack Fabrics: What You Need to Know Before You Buy
Introduction to Backpack Fabrics
Choosing the right backpack fabrics is essential for any traveler, nomad, or adventurer. One of the most critical factors to consider when selecting a backpack are the fabrics used within its construction. Quality matters, especially when traversing through different environments.
Backpack fabrics play a significant role in the durability, weight, and overall performance of your bag.
In this guide, we will explore the most common materials used in backpack construction, including nylon, polyester, Cordura®, X-Pac®, Ecopak®, Dyneema®, and Kodra, and explain the pros and cons of each. Hopefully it helps you to make an informed decision when purchasing your next backpack.
Nylon: The Classic Choice
Nylon (a synthetic polymer) is one of the most popular choices for backpack fabrics due to its impressive balance of strength, durability, and affordability.
There are two primary types of nylon used in backpacks: nylon 6 and nylon 6,6. Both have similar properties, but nylon 6,6 is considered to be slightly stronger and more durable.
Nylon is created by a process called polymerization, where monomers are combined to form long chains called polymers. The material is then woven into a fabric, often using various weaves, such as plain or ripstop, to enhance its properties. Ripstop nylon, for example, is woven with a reinforcing pattern that makes it resistant to tearing.
Nylon's strength is often measured in deniers (D), which indicates the fiber's linear mass density. The higher the denier count, the thicker and stronger the nylon.
However, a higher denier also means increased weight, so it's essential to strike a balance between strength and weight when choosing a backpack.
Pros
- High strength and durability
- Abrasion-resistant
- Lightweight
- Generally affordable
Cons
- Not inherently waterproof
- May be less UV resistant compared to polyester
Thought-Provoking Question: Are you looking for a backpack that can withstand everyday wear and tear? If so, nylon might be the perfect choice for you.

Polyester: A Popular Alternative
Polyester is another widely used synthetic fabric in backpack manufacturing. It is made from petroleum-derived chemicals, formed through a process called polymerization, similar to nylon. Polyester fibers are then woven into various fabrics, such as plain weave or ripstop.
Compared to nylon, polyester tends to have a higher resistance to ultraviolet (UV) degradation, making it a suitable choice for sunny conditions. However, its strength-to-weight ratio is generally lower than that of nylon, meaning that a polyester backpack of similar strength will typically be heavier.
Polyester's strength is also measured in deniers, like nylon. The material is often treated with a water-repellent coating to enhance its water resistance, but it is not inherently waterproof.
Pros
- Durable and abrasion-resistant
- Good UV resistance
- Lightweight
- Dries quickly
Cons
- Lower strength compared to nylon of similar denier
- Not inherently waterproof
Are you planning to use your backpack in sunny conditions? If so, the UV resistance of polyester may make it a more suitable option.
