For over 15 years, our company has specialized in manufacturing and customizing high-quality tactical gear, including bags, vests, modular pouches, and more. As a trusted supplier, we know the importance of quality materials in the performance and durability of our products. One such material is waterproof fabric.
This guide explores waterproof fabric technologies, their applications, and how they meet the needs of tactical, military, and outdoor gear.
Su Geçirmez Kumaş Nedir?
Waterproof fabric is engineered to block water penetration under specific conditions, ensuring gear remains dry during demanding missions or harsh weather. Unlike vague marketing terms, waterproofing is measured by the hydrostatic head rating, which indicates the water pressure (in millimeters) a fabric can withstand before leaking. For example:
- 1,500–5,000mm: Suitable for moderate rain and light tactical gear.
- 5,000–10,000mm: Ideal for heavy rain and tactical backpacks.
- 10,000mm+: Designed for extreme conditions, such as high-altitude expeditions.
This performance standard ensures your gear, from serious tactical backpacks to outdoor apparel, meets the demands of real-world use.

How Waterproof Fabrics Work
Waterproof fabrics create a barrier to liquid water while, in many cases, allowing water vapor (sweat) to escape for breathability. This is achieved through:
- Dayanıklı Su İtici (DWR) Treatment: Applied to the outer fabric, DWR causes water to bead and roll off, preventing saturation. Without DWR, a waterlogged outer layer can reduce comfort and breathability, though the waterproof barrier remains effective.
- Membranes or Coatings: A laminated membrane (e.g., ePTFE) or coating (e.g., PU) has microscopic pores that block liquid water but allow vapor to pass, balancing waterproofing and breathability.
- Mühürlü Dikişler: All stitch holes are sealed to prevent water ingress, critical for true waterproof performance.
Waterproof vs. Water-Resistant Fabrics
Understanding the difference between waterproof and water-resistant fabrics is helpful for designing tactical gear that performs as expected.
- Waterproof Fabrics: These provide a guaranteed barrier against water, even in sustained heavy rain. They include a membrane or coating and sealed seams, making them ideal for military-grade gear like tactical vests or MOLLE-compatible packs.
- Water-Resistant Fabrics: These resist light moisture, such as drizzle, using a DWR finish or tight weave. They’re suitable for casual outdoor jackets or gear for brief exposure, but will eventually get wet through. They lack high hydrostatic head ratings.

Here are the primary waterproof materials used in tactical gear manufacturing, each suited to specific applications:
- ePTFE Membranes (e.g., GORE-TEX®)
Expanded Polytetrafluoroethylene (ePTFE) membranes, such as GORE-TEX, are a premium choice. With over 9 billion microscopic pores per square inch, these membranes are highly waterproof (20,000 times smaller than a water droplet) and breathable (700 times larger than a water vapor molecule).
Performance: Exceptional waterproofing and breathability.
Applications: High-performance tactical clothing, mountain expedition packs, and elite military gear.
- PU-Coated Fabrics
Polyurethane (PU) coatings are applied to fabrics like nylon or polyester, creating a non-porous, waterproof layer. Modern micro-porous PU coatings improve breathability.
Performance: Reliable waterproofing with moderate breathability, and cost-effective.
Applications: Widely used in modüler poşetler, utility belts, soft gun cases, and affordable rain gear.
- TPU-Laminated Fabrics
Thermoplastic Polyurethane (TPU) laminates offer durability, elasticity, and eco-friendly options (solvent-free). They remain flexible in cold temperatures and resist abrasion.
Performance: High durability, flexibility, and moderate breathability.
Applications: Heavy-duty load-bearing vests, dog harnesses, and protective equipment cases.
- PVC Kaplı Polyester
Polyvinyl Chloride (PVC) coatings create a heavy-duty, fully impermeable barrier, resistant to abrasion, chemicals, and tearing.
Performance: Ultimate waterproofing, but non-breathable and heavier.
Applications: Heavy-duty duffel bags, equipment tarps, and protective gear covers.
Considerations: Stiff in cold weather, best for non-apparel items.
Applications in Tactical Gear Manufacturing
Here’s how we apply these technologies in our products:
- Tactical Apparel: For military jackets and pants, 3-layer ePTFE laminates provide breathability and protection for high-intensity operations.
- Tactical Packs and Bags: TPU laminates are used in hydration bladders for taste-free, flexible performance, while PU-coated high-denier nylon suits MOLLE-compatible packs.
- Protective Covers: PVC or heavy PU coatings protect soft rifle cases and optical gear from moisture and rough handling.
- Kılıflar ve Kemerler: Water-resistant PU coatings prevent moisture damage and mildew, ensuring reliable duty belt systems.
- Dog Vests and Harnesses: TPU laminates offer durability and flexibility for working canines in wet environments.
We also consider environmental impact, opting for solvent-free TPU where possible to meet sustainability goals.

Sonuç
The ideal waterproof material depends on the intended use, performance requirements, and budget of the final product. For elite tactical outerwear, ePTFE membranes like GORE-TEX excel. For rugged, cost-effective gear, PU or TPU coatings are versatile. For heavy-duty protection, PVC is unmatched.
Our team, with over 15 years of expertise, guides our partners to select materials that meet performance standards like ISO 811 for hydrostatic head testing.
