Waterproof Breathable Fabric

Advanced Waterproof Breathable Fabric for High-Performance Outdoor Garments

Our Waterproof Breathable Fabric represents the cutting edge of technical textile engineering, designed for extreme weather conditions where protection and comfort are equally critical. As the premium tier of our Waterproof & Breathable Fabric collection, this material solves the fundamental challenge of outdoor apparel: keeping the wearer dry from external rain while simultaneously allowing internal moisture (sweat vapor) to escape.

The Science of Breathable Waterproofing

Unlike traditional waterproof coatings that trap heat and moisture, our breathable fabric utilizes a micro-porous membrane (PU or TPU). The microscopic pores are smaller than a water droplet (preventing rain from entering) but larger than a water vapor molecule (allowing sweat to evaporate). This ensures that athletes and outdoor enthusiasts remain dry from both the outside environment and their own internal body heat, significantly reducing the "clammy" feeling common in non-breathable gear.

Lamination Technologies: 2-Layer vs. 3-Layer

To meet the diverse needs of manufacturers, we offer two primary lamination structures:

• 2-Layer (2L): Bonds the breathable membrane to the face fabric with a separate "hanging" liner. This offers maximum durability and is ideal for heavy-duty jackets, workwear, and industrial protection.
• 3-Layer (3L): Sandwiches the membrane between the face fabric and a durable backer. This eliminates the need for a separate lining, resulting in a significantly lighter, more packable, and flexible fabric perfect for high-end mountaineering and travel gear.

Performance Standards and Testing

We ensure every roll meets rigorous international testing protocols to guarantee reliability in the field:

1. Hydrostatic Head Test (EN ISO 811): Confirms waterproof ratings between 10,000mm and 20,000mm for true rain and snow protection.
2. Moisture Vapor Transmission (MVTR): Measured to ensure breathability rates exceeding 5,000 g/m²/24h, keeping the wearer cool during high exertion.
3. DWR Surface Testing: Verified to ensure water beads up and rolls off the fabric surface, maintaining breathability throughout the garment's life.
4. Seam Taping Adhesion: Tested to ensure the membrane bonds securely to seam tape, preventing water ingress at stitch lines.

Ideal Applications

This versatile technical fabric is the industry standard for:

• High-Performance Outerwear: Ski jackets, mountaineering shells, and hardshell pants
• Travel & Commuter Gear: Packable rain jackets and windbreakers
• Medical & Protective Clothing: Waterproof surgical gowns and sterile barriers
• Technical Accessories: Rain covers, backpack protective sheets, and camping gear

Why Choose Our Technical Fabric?

By offering both PU (Polyurethane) and TPU (Thermoplastic Polyurethane) membrane options, we provide flexibility in hand-feel and environmental impact. Our fabrics are OEKO-TEX certified, ensuring they are free from harmful chemicals, making them safe for direct skin contact and compliant with global environmental standards.
