We understand the frustration of a backpack that fails prematurely. Whether it’s a torn strap, a broken zipper, or a hole worn through the bottom, a poorly made backpack can disrupt your day and cost you money in the long run. A key factor in a backpack’s longevity is the material it’s made from, and nylon is a dominant player in the backpack world.
But not all nylon is created equal. Different weaves, treatments, and denier ratings significantly impact durability and performance.
This post aims to provide a comprehensive overview of nylon as a backpack material, helping you understand the nuances and confidently choose the best nylon for durable everyday backpacks that meet your specific needs. We will examine the specifics of various nylon types, examining their strengths and weaknesses.
Understanding Nylon: The Backbone of Many Backpacks
Nylon, a synthetic polymer, is prized for its strength, durability, and water resistance, making it an ideal fabric for backpacks. But the term “nylon” encompasses a range of materials. We often see it described with terms like “ripstop,” “ballistic,” or “Cordura,” and numbers followed by the letter “D” (e.g., 500D, 1000D). These descriptors are crucial to understanding a backpack’s potential performance.
The “D” stands for Denier, a measurement unit that indicates the fibers’ linear mass density. A higher denier generally means a thicker, coarser, and more robust fabric.
However, denier isn’t the only factor. The weave and any coatings applied also play significant roles. For example, a 420D nylon with a tight weave and a water-resistant coating might outperform a loosely woven 600D nylon. We need to look at the complete picture.
Common Nylon Types and Their Properties
Let’s examine some of the most common nylon types found in backpacks:
Ripstop nylon. Often seen in lighter-weight backpacks, ripstop nylon features a grid pattern of reinforcing threads woven into the fabric. This grid helps to prevent small tears from spreading, hence the name “ripstop.” While it can be found in various denier ratings, it’s often used when weight is a primary concern, such as ultralight hiking backpacks or packable daypacks.
Ballistic nylon. Originally developed for flak jackets during World War II, ballistic nylon is known for its exceptional abrasion resistance and tear strength. It’s typically a heavier, higher-denier nylon (often 1050D or higher).
While incredibly tough, it can be less flexible than other types. Ballistic nylon is an excellent choice for backpacks with heavy use and potential abrasion, such as a rugged travel backpack or a work bag for carrying tools. Ballistic nylon is frequently featured in lists detailing the best for durable everyday backpacks.
Cordura nylon. Cordura is a brand name for various fabrics, many of which are nylon-based (though some are nylon/cotton blends). Cordura is known for its durability and resistance to abrasions, tears, and scuffs. It’s often used in high-quality backpacks, workwear, and military gear. Like ballistic nylon, it comes in various denier ratings.
Packcloth nylon. This is a catch-all name for various Nylons, typically designed for use in packs and bags. It usually has a waterproof coating, making it more durable and resistant to the elements. This coating is often polyurethane (PU), which adds a layer of protection against moisture and abrasion. Packcloth nylon is frequently found in mid-range deniers, offering a good balance of weight and strength.
Denier and its Impact on Durability
As mentioned, denier is a crucial factor. Here’s a general guideline for denier ratings in backpacks:
Denier (D) | Common Fabric Type(s) | Characteristics |
70D | Ripstop Nylon (often with PU coating) | Very lightweight, less abrasion-resistant, good for occasional use, often water-resistant due to coating. |
210D | Ripstop Nylon (often with PU coating) | Good balance of weight and durability, more abrasion-resistant than 70D, often water-resistant. |
420D | Packcloth Nylon, sometimes Ripstop | Durable, good abrasion resistance, a common choice for general-purpose backpacks. |
500D | Cordura Nylon, Packcloth Nylon | Excellent abrasion resistance, heavier than 420D, suitable for heavier loads and more demanding use. |
600D | Polyester, Packcloth Nylon | Excellent abrasion resistance, heavier, suitable for heavier loads and more demanding use. |
840D | Ballistic Nylon, sometimes Cordura | Very high abrasion resistance, heavier, designed for rough handling. Often has a robust, textured feel. |
1000D | Cordura Nylon | Highest abrasion resistance, heaviest common option, built for extreme durability. |
1050D | Ballistic Nylon | Originally designed for flak jackets. Exceptionally tough and abrasion-resistant. Very stiff and heavy. |
1680D | Ballistic Nylon | Designed for extreme durability, great abrasion resistance. |
It’s important to remember that these are general guidelines. The specific weave and applied coatings (like polyurethane for water resistance) will also influence the fabric’s overall performance.
Nylon Denier Suitability for Different Backpack Types
The ideal denier depends heavily on the backpack’s purpose. A school backpack carrying light books requires a different fabric strength than a hiking backpack to withstand harsh conditions and heavy loads. This section guides selecting appropriate nylon denier ranges for various backpack categories.
Backpack category | Suitable denier range | Explanation |
School backpacks | 400D – 600D | Balances durability for daily wear and tear with a reasonable weight for younger users. Textbooks, notebooks, and occasional heavier items are accommodated without excessive bulk. |
Work backpacks | 500D – 1000D | Requires greater durability to withstand daily commutes, often carrying laptops, documents, and potentially heavier items. Higher deniers offer better protection against abrasion and potential punctures. |
Commuter backpacks | 400D – 840D | Similar to work backpacks, but may prioritize lighter weight and water resistance over maximum durability. A balance between protection, weight, and resistance to the elements is struck. |
Travel backpacks | 700D – 1680D | Needs high durability to withstand rough handling during travel (e.g., checked baggage, overhead compartments). Higher deniers provide superior tear and abrasion resistance, protecting contents during long journeys. |
Hiking backpacks | 420D-2000D | Requires the highest durability to endure harsh outdoor conditions, heavy loads, and potential contact with rocks and branches. Often includes a ripstop weave for added tear resistance. Heavier fabric in high wear and tear areas. |
Everyday carry (EDC) backpacks | 400D – 1000D | Versatile range depending on individual needs and preferences. Lower deniers offer a lighter, more compact option, while higher deniers provide increased durability for those who carry heavier items or are rougher on their bags. |
Sports backpacks | 400D – 840D | Depends on the specific sport. Gym bags may use lower deniers for lightweight carrying, while bags for outdoor sports or carrying heavier equipment (e.g., climbing gear) will benefit from higher deniers. |
Other Considerations: Water Resistance, Zippers, and Stitching
While the type of nylon is paramount, other factors contribute to a backpack’s overall durability.
Water resistance. Nylon is somewhat water-resistant, but look for backpacks with a DWR (Durable Water Repellent) coating or a polyurethane (PU) coating on the inside for better protection. These coatings will help repel water and protect your belongings.
Zippers. A strong fabric is useless if the zippers fail. Look for high-quality zippers from reputable brands like YKK. Larger, self-repairing zippers are generally more durable. Pay close attention to the zipper’s teeth and slider; a robust and smooth-operating zipper is a sign of quality construction.
Stitching. Reinforced stitching is crucial, particularly at stress points like the shoulder straps and bottom of the bag. Bar-tack stitching (a series of close, tight stitches) is a good indicator of quality construction. We examine these details to identify the best nylon for durable everyday backpacks.
Conclusion
Choosing the best nylon for durable everyday backpacks involves understanding the interplay of denier, weave, and additional features like water-resistant coatings. While higher denier generally indicates greater durability, it’s not the sole determining factor.
Consider your intended use: a lightweight daypack might be perfectly fine with 420D ripstop nylon, while a heavy-duty travel backpack might benefit from 1050D ballistic nylon. Pay attention to the details – zippers, stitching, and overall construction – to ensure you’re investing in a backpack that will withstand the rigors of daily life. We hope this guide has empowered you to make an informed decision.
