How to Choose a Waterproof Jackets Manufacturer: Materials, Tests, and MOQ

For fashion brands and wholesalers, this rising demand creates an incredible opportunity. But success depends on one critical decision: choosing the right Waterproof Jackets Manufacturer.

A professional manufacturer not only produces garments but also safeguards your brand reputation. The right partner ensures waterproof performance, consistent quality, reliable delivery, and long-term scalability. In contrast, choosing the wrong one could mean delayed shipments, product failures, or even lost customers.

This guide will show you how to evaluate a Waterproof Jackets Manufacturer, focusing on materials, performance tests, and MOQ (Minimum Order Quantity) — the three factors that define production success.

1.Hydrostatic pressure testing

2.Seam sealing and bonding

3.Breathability control

4.Coating or membrane layering

Only manufacturers with the right experience and certification can manage this complexity. When evaluating potential suppliers, ask yourself:

1.Do they understand waterproof performance beyond marketing terms?

2.Can they translate your brand’s designs into technical patterns?

3.Are they ISO-certified and ethically compliant?

4.Can they handle both small test runs and large wholesale volumes?

At Ginwen, we answer “yes” to all of these questions. As a professional Waterproof Jackets Manufacturer with over 20 years of experience, we support brands worldwide with OEM & ODM production services, from fabric sourcing to final shipment.

Our mission is to make premium waterproof apparel accessible to brands of all sizes — from boutique designers to international retailers.

When choosing a Waterproof Jackets Manufacturer, the first factor to evaluate is material technology. A jacket’s performance depends largely on the fabrics and membranes used to keep moisture out while allowing breathability.

A professional manufacturer understands not just sewing but also the science of waterproofing — knowing how fabrics behave under pressure, humidity, and movement.

The most common waterproof materials used in custom waterproof jackets include:

Polyurethane-coated nylon is lightweight, affordable, and ideal for fashion or light outdoor jackets. It provides basic water resistance with a hydrostatic head rating of 5,000–10,000 mm H₂O.

Polyester fabrics with laminated membranes offer stronger waterproofing and durability, suitable for sportswear and hiking jackets. They often achieve ratings between 10,000–20,000 mm H₂O.

High-end outdoor collections often use 3-layer constructions that combine a durable face fabric, waterproof-breathable membrane, and inner lining. These fabrics provide superior water resistance and breathability, comparable to branded materials like GORE-TEX®.

As sustainability becomes a major priority, many brands now demand eco-conscious materials such as recycled polyester or organic cotton with PFC-free coatings. A skilled Waterproof Jackets Manufacturer should offer these options while maintaining performance integrity.

At Ginwen, we source from verified mills that provide OEKO-TEX®-certified fabrics and recyclable membranes, helping brands align with modern environmental standards.

At Ginwen, we test every fabric for hydrostatic pressure, breathability (g/m²/24hr), and tear strength before production. This ensures that our custom waterproof jackets perform reliably across climates and activities.

A fabric with a rating of 5,000–10,000 g/m²/24hr is suitable for casual wear, while 15,000–25,000 g/m²/24hr supports high-intensity outdoor activities.

As an experienced Waterproof Jackets Manufacturer, Ginwen balances waterproofing with breathability through advanced lamination and seam-sealing techniques. Our jackets maintain dry comfort even under demanding conditions.

We also use taped seams and YKK or SBS waterproof zippers to eliminate leakage points — small details that significantly impact performance.

DWR (Durable Water Repellent): A surface treatment causing water to bead off easily.

Anti-wrinkle finish: Keeps fabric smooth and stylish for fashion applications.

UV protection coating: Adds sun resistance for outdoor adventures.

Reinforced panels: Extra durability on shoulders and elbows for active use.

At Ginwen, we integrate these finishing technologies into our OEM & ODM production lines based on brand requirements — from minimalist fashion bombers to heavy-duty mountaineering shells.

🔗 OEM & ODM Service

All fabrics are pre-tested for hydrostatic pressure and breathability.

We maintain long-term partnerships with certified mills.

Every project includes a full material data sheet for transparency.

This guarantees that our clients receive not just waterproof jackets, but technically engineered garments designed to last.

A true Waterproof Jackets Manufacturer goes far beyond cutting and sewing — it’s about engineering performance. Testing ensures every product can withstand real-world conditions such as heavy rain, wind, and humidity without failure.

At Ginwen, we integrate testing throughout the entire production process to guarantee durability and consistency for our custom waterproof jackets.

This test measures the fabric water resistance by determining how much pressure it can handle before leaking. Each fabric batch used in Ginwen’s production is tested to meet a minimum rating of 10,000–20,000 mm H₂O, depending on client requirements.

Even if the fabric is waterproof, poorly sealed seams can cause leaks. We test seam tape adhesion strength and ensure bonding durability through high-frequency heat-sealing technology.

Zippers are common failure points. Ginwen uses YKK or SBS waterproof zippers and performs submersion tests to ensure water-tight performance under movement.

A jacket must block rain yet release heat and moisture. Using standardized Moisture Vapor Transmission Rate tests, we verify breathability levels of 5,000–25,000 g/m²/24h, suitable for both daily wear and professional sports applications.

Beyond the lab, our QA team conducts real-condition wear tests — simulating rain and motion to assess comfort, flexibility, and seam reliability.

These testing protocols are critical for any brand seeking to collaborate with a reliable Waterproof Jackets Manufacturer. They ensure the finished product not only meets technical specs but also delivers customer satisfaction.

At Ginwen, we apply a multi-stage QC framework that begins even before production starts.

Inspect incoming fabrics for color consistency, coating quality, and hydrostatic performance.

Approve trims and zippers based on brand specifications.

Validate patterns using CAD fitting simulations.

Dedicated inspectors monitor sewing lines for precision in stitching, seam sealing, and trimming.

Any deviation is corrected immediately to prevent downstream defects.

Each custom waterproof jacket undergoes a comprehensive inspection covering:

Seam sealing integrity

Zipper functionality

Fabric surface and color

Fit and measurement tolerance

Label and packaging accuracy

Every piece leaving Ginwen’s facility is verified against AQL (Acceptable Quality Limit) standards and accompanied by inspection reports for brand documentation.

To further enhance transparency, our digital management system tracks production progress in real time — from cutting to final inspection. This enables clients to receive accurate updates without delays or communication gaps.

It defines how accessible and flexible your production partnership will be.
