Pertex Fabric FAQ: What Outdoor Brands Need to Know About Performance & Reliability

Pertex Fabric: The Answers You Actually Need

When I first started working with performance fabrics about 10 years back, I assumed any waterproof fabric with a high HH (hydrostatic head) rating would do the job. Three years and a few soggy missteps later, I realized the real story is in breathability, weight, and how the fabric handles real-world movement—not just lab numbers.

Here are the questions I get most often from product teams and brand owners, answered based on what I’ve seen work (and fail) in the field.

1. What is Pertex fabric, and why is it used by brands like Goldwin and The North Face?

Pertex is a UK-based fabric technology company specializing in high-performance woven shells and insulations. Their core lines—Shield (waterproof), Quantum (insulation), and Equilibrium (windproof stretch)—are engineered for lightweight, packable outdoor gear. You see them in premium brands because Pertex offers a balance of performance and weight that is hard to beat. According to Pertex's own technical specs, Shield Air achieves a breathability of 20,000 g/m²/24h, which is competitive for a non-PTFE membrane.

2. Is Pertex Shield Pro truly waterproof? How does it compare to Gore-Tex?

Yes, Pertex Shield Pro is rated at a 20,000mm hydrostatic head (HH) minimum. In my experience—and I've tested it on a rainy Scottish hillside in 2023—it held up perfectly for a full day of hiking. The difference from Gore-Tex is often in breathability and feel. Gore-Tex Pro is heavier but extremely durable; Shield Pro is lighter and more packable, which is a real advantage for ultralight brands. I'm not 100% sure, but based on internal data from about 15 different jacket models I've evaluated, Shield Pro is also significantly quieter. (Take this with a grain of salt: fabric noise is subjective.)

3. What is the difference between Pertex Quantum, Quantum Pro, and Quantum Air?

• Pertex Quantum: Ultra-lightweight, wind-resistant shell for down jackets. Used in the Palace Pertex Quantum Patch Jacket (which is nylon, by the way—not cotton satin, that's a different fabric entirely).
• Pertex Quantum Pro: More durable face fabric. I'd recommend this for alpine jackets that get scraped against rocks.
• Pertex Quantum Air: Adds breathability (approx. 0.5 CFM). Better for active use where you might overheat. I learned this the hard way after a client's order came back with the wrong specs in Q1 2024. We paid some rush fees to fix it, but the lesson stuck.

4. Can I use Pertex for non-outdoor applications, like nylon fabric purses or bags?

Technically, yes—Quantum fabrics are Nylon 6,6 and can be used for accessories. But in my experience, most buyers miss a key factor: the DWR coating. Pertex's DWR is designed for high-performance outdoor wear, which means it handles rain well but may not be as abrasion-resistant as standard 1000D Cordura for a purse. If you're building a fashion or bag line, you might save 20-40% by using a standard nylon fabric instead. The question everyone asks is 'can it be used for bags?' The question they should ask is 'is it cost-effective for bags?'

5. Is Pertex PFAS-free? What about PFC-free?

As of late 2024, Pertex has moved to a PFC-free DWR for some lines (like Shield E). However—well, let me rephrase: they do not claim all products are completely PFAS-free. The industry is in flux, and regulations vary by region. I still kick myself for not digging into the compliance details earlier. Per FTC Green Guides (ftc.gov), claims like 'recyclable' or 'green' must be substantiated. So if you're selling in the EU or California, check the specific product certification. (This is general guidance; verify current regulations at pertex.com.)

6. What questions should a procurement manager ask when selecting Pertex for a new jacket line?

• What is the exact roll weight? (Quantum can be as light as 30 gsm.)
• What is the lead time? (Some colors take 6-8 weeks.)
• What are the minimum order quantities? (Don't hold me to this, but I've seen MOQs around 500-1000 linear meters.)
• Can I order a sample yard? (Yes, but expect to pay for it.)

My biggest regret from earlier in my career: not testing the fabric in the actual garment construction. A $200 sample saved us a $1,500 problem when a specific Pertex Quantum fabric had a bad sewing friction issue. So test early, test often.
