When embarking on an outdoor adventure, or even just navigating the daily commute, the reliability of your backpack is paramount. We understand the frustration of a ripped seam, a soaked interior, or a bag that simply doesn’t hold up to the rigors of daily use.
A critical, often overlooked, component contributing to a backpack’s resilience is the fabric it’s made from: packcloth nylon. But with various types and specifications available, how do you discern the best packcloth nylon for your needs?
This comprehensive guide delves into the nuances of packcloth nylon, exploring its properties, variations, and key considerations to empower you to make an informed decision and select a backpack built to last. We will arm you with the knowledge needed to choose wisely.
Understanding Packcloth Nylon
Packcloth nylon is a woven fabric specifically engineered for durability and abrasion resistance, making it a popular choice for backpacks, luggage, and outdoor gear. Unlike cotton or canvas, nylon is a synthetic polymer that inherently resists tearing and wear.
However, not all packcloth nylon is created equal. Several factors contribute to its overall performance. The weave itself may differ in density and pattern. A tighter weave provides greater strength, at a cost of slightly higher weight.
Several specific grades and treatments of nylon are common in backpack construction, each offering a unique balance of properties. These variations primarily concern the denier of the yarn, the presence and type of coatings, and any additional treatments, such as ripstop weaving. These characteristics will be discussed in detail. Let’s move on to the first important factor, denier.
Deciphering Denier: A Measure of Yarn Thickness
One of the most frequently encountered terms when researching packcloth nylon is “denier” (often abbreviated as “D”). Denier refers to the linear mass density of the fibers – essentially, the thickness and weight of the yarn used to weave the fabric. A higher denier number indicates a thicker, heavier, and generally more robust yarn.
For example, 420D nylon is commonly used in the main body of many backpacks, offering a good balance of durability and weight. A 1000D nylon, like that sometimes used for Cordura® fabric, is significantly thicker and more abrasion-resistant, often found in high-wear areas like the bottom of a pack. However, it also adds weight.
We want to stress that a higher denier isn’t always better. A lower denier nylon, such as 210D or even 70D (often used in pack linings or ultralight gear), can be perfectly suitable for applications where weight is a primary concern and extreme abrasion resistance isn’t critical. The appropriate denier depends heavily on the intended use of the backpack. Choosing the wrong denier may result in an overweight bag, or one that fails too early.
The Importance of Coatings: Enhancing Water Resistance and Durability
While nylon has some inherent water resistance, most packcloth nylon receives additional coatings to enhance this property and improve its overall durability. We typically see two main types of coatings applied to backpack fabrics:
- Polyurethane (PU) Coatings: PU coatings are applied to the inside of the fabric, creating a waterproof barrier. They are relatively inexpensive and effective at preventing water penetration. However, PU coatings can degrade over time, especially with exposure to UV light and abrasion. The quality of the PU coating can vary significantly, affecting its long-term waterproofness and resistance to delamination (peeling). Look for multiple layers of coating for better durability.
- Durable Water Repellent (DWR) Coatings: DWR coatings are applied to the outside of the fabric, causing water to bead up and roll off rather than soaking in. DWR coatings are not inherently waterproof, but they significantly improve the fabric’s ability to shed water and prevent it from becoming saturated. DWR coatings also help to repel dirt and stains. DWR, like PU, can degrade over time but is reapplicable.
Many high-quality backpacks utilize both PU and DWR coatings for optimal water resistance. The PU coating provides a waterproof barrier, while the DWR coating helps to protect the PU coating and keep the outer fabric from becoming waterlogged.
Ripstop Nylon: Preventing Tears from Spreading
Another important consideration is whether the packcloth nylon incorporates a “ripstop” weave. Ripstop nylon features a grid pattern of heavier reinforcement threads interwoven regularly. This grid pattern helps to prevent small tears or punctures from spreading. If a rip does occur, it is typically contained within one of the small squares of the grid, minimizing the damage.
We believe ripstop nylon is valuable for backpacks, especially those intended for outdoor use or heavy loads. While it adds a small amount of weight, the increased tear resistance can significantly extend the pack’s lifespan. Look for ripstop patterns, a visible grid on the fabric’s surface.
Choosing the Right Packcloth Nylon for Your Needs
Ultimately, the “best” packcloth nylon for your backpack depends on your specific needs and priorities. Consider the following factors:
- Intended use: Are you planning on using the backpack for everyday carry, hiking, travel, or something else? The demands of each activity will influence the ideal fabric choice.
- Weight capacity: How much weight will you carry in the backpack? Heavier loads require more durable fabric.
- Weather conditions: Will you use the backpack in wet or snowy conditions? Prioritize water resistance and consider a combination of PU and DWR coatings.
- Budget: Higher-quality packcloth nylon with advanced coatings and ripstop weaves will typically be more expensive.
- Abrasion resistance: How rough will you be on your pack? Will it frequently brush against rocks, branches, or other abrasive surfaces?
A good starting point for a general-purpose backpack is 420D nylon with a PU coating and DWR finish. For more demanding applications, consider 500D or even 1000D nylon, especially for areas that experience high wear, like the bottom of the pack. For ultralight backpacking, 210D or even lower denier nylon with a DWR finish might be sufficient.
Packcloth Nylon for Backpacks: A Suitability Overview
Packcloth nylon is a popular fabric choice for backpacks, known for its balance of durability, water resistance, and affordability. However, its specific suitability varies depending on the intended use of the backpack. This breakdown explores packcloth nylon’s strengths and weaknesses across different backpack categories. The denier of the nylon has not been defined, so this description will use generalities about packcloth.
| Backpack type | Suitability level | Pros | Cons |
| School backpacks | Good | Abrasion-resistant, lightweight, water-resistant, affordable. | May not be robust enough for very heavy loads or sharp objects; higher-denier nylon might be better for extreme use. |
| Work backpacks | Generally Suitable | Professional appearance, decent durability, water-resistant. | May not offer the premium look and feel of materials like ballistic nylon or canvas. |
| Commuter backpacks | Very Good | Durable, water-resistant, lightweight, handles daily wear and tear well. | No significant cons for typical commuting needs. |
| Travel backpacks | Decent/Limited | Durable enough for general travel, water-resistant, suitable for carry-on. | May not be ideal for checked luggage (high abuse); more waterproof material or rain cover needed for harsh weather. |
