| X-Grid Reinforcement | Polyester Fibers | N/A (fiber mesh) | 10 – 20 | Tear resistance, structural strength |
| Waterproof Membrane | PET Film | 0.015 – 0.035 | N/A | Waterproofing, windproofing |
| Inner Backing Layer | Nylon/Polyester | 0.10 – 0.15 | 50 – 80 | Protects membrane, adds durability |
X-Pac fabric is a high-performance multi-layer composite material, designed to balance durability, waterproofing, and lightweight properties. Its structure typically consists of four main layers, each contributing to its unique performance:
Usually made from 210D or 330D nylon with a ripstop weave for enhanced abrasion resistance.
Provides the first line of defense against wear and UV exposure.
Thickness: approximately 0.12–0.20 mm.
Weight: around 60–90 g/m².
X-Grid Reinforcement Layer
A grid of polyester fibers laminated inside the fabric in a distinctive “X” pattern at a 45-degree angle.
This layer dramatically improves tear resistance, allowing the material to resist propagation of rips and punctures.
Polyester fibers typically have a denier of 70–150D depending on the model.
This reinforcement adds minimal weight (~10–20 g/m²) but significant structural strength.
Waterproof PET (Polyester) Film Membrane
A thin, continuous film laminated between fabric layers to provide complete waterproofing.
Typical thickness ranges from 0.015 mm to 0.035 mm depending on the product variant.
This membrane also ensures windproofing and breathability varies by layer construction.
Backing Nylon or Polyester Layer
The innermost layer is usually a lightweight nylon or polyester fabric, providing support and protecting the membrane from abrasion from inside.
Thickness similar to the outer layer, generally 0.10–0.15 mm.
Weight: roughly 50–80 g/m².
X-Pac fabric comes in several variants such as VX07, VX21, and VX42, each differing in layer thickness and weight to suit specific backpack applications—from ultralight hiking packs to heavy-duty tactical gear. When selecting X-Pac for backpack production, manufacturers should carefully consider these differences to balance durability, weight, and flexibility according to the target use.
The fabric’s unique lamination process fuses the multiple layers seamlessly, resulting in a material that offers exceptional tear resistance and waterproof performance without compromising flexibility. This ensures that backpacks made with X-Pac maintain their shape and durability even under demanding outdoor conditions.
Comparison of X-Pac and Other Common Backpack Fabrics
After learning about the structure and performance of each layer in X-Pac fabric, many customers still wonder: how does it actually compare to common materials like standard nylon or Oxford cloth?
| Fabric Type | Advantages | Disadvantages |
|---|---|---|
| X-Pac | Lightweight, waterproof, tear-resistant, holds shape well | Higher cost, stiff texture, less flexible |
| Cordura | Extremely durable and abrasion-resistant, handles heavy loads | Weaker waterproofing, usually needs extra coating |
| Oxford | Good texture, reasonably priced, decent durability | Moderate waterproofing, absorbs water, relatively heavy |
| Canvas | Strong and durable, eco-friendly, classic look | Not waterproof, gets dirty easily, slow to dry, heavy |
In fact, X-Pac stands out not only for its superior waterproof and tear-resistant properties, but also for its unique multi-layer laminate construction, which allows it to remain lightweight while offering exceptional strength and shape retention.
Traditional nylon and Oxford fabrics do offer decent abrasion resistance, but they generally fall short in terms of waterproofing, tear resistance, and structural rigidity—especially when used in high-performance or outdoor gear applications.
