A Brief History of Gore-Tex
The story of Gore-Tex begins in the early 1960s. Bob Gore, a chemical engineer at W. L. Gore & Associates, was experimenting with a polymer called expanded polytetrafluoroethylene (ePTFE) – a material that’s lightweight, flexible, and has a high melting point.
In 1969, Bob made a breakthrough: by stretching ePTFE, he created a microporous membrane with billions of tiny holes. These pores were small enough to block liquid water but large enough to let water vapour escape. It was both waterproof and breathable – a revolutionary concept at the time.
The first Gore-Tex rain jacket soon followed and became an instant favourite among outdoor enthusiasts. Over the years, the brand expanded into shoes, gloves, tents, backpacks, and more. Today, Gore-Tex remains one of the most trusted materials in the outdoor world.
How Gore-Tex Works
Gore-Tex relies on a membrane made of expanded polytetrafluoroethylene (ePTFE). This membrane is packed with billions of microscopic pores that are small enough to block liquid water but large enough to let water vapour escape.
When rain hits the surface of the fabric, the droplets bead and roll off, thanks to a durable water-repellent (DWR) finish on the outer layer. At the same time, sweat generated inside the garment passes through the membrane’s pores, keeping you dry and preventing that clammy feeling.
Another important property of Gore-Tex is windproofing. By stopping cold air from penetrating the fabric, it helps the wearer maintain warmth even in harsh weather.
Many Gore-Tex products also feature additional DWR treatments to enhance water resistance, making them more effective in prolonged wet conditions.
In short, Gore-Tex provides a reliable balance of waterproofing, breathability, and wind protection, making it a benchmark material for outdoor gear.
Where Gore-Tex Is Used
Gore-Tex is used across a huge range of outdoor gear and apparel. You’ll find it in jackets, pants, gloves, hats, shoes, and even backpacks — anywhere reliable waterproofing and breathability matter. It’s a go-to material for hiking, skiing, mountaineering, and any activity where staying dry is essential.
One of Gore-Tex’s biggest advantages is its durability. The fabric resists abrasion and stands up well to rugged terrain, which is why so many top outdoor brands rely on it for their premium products. Over the years, it’s become almost synonymous with high-performance gear.
Beyond the trail, Gore-Tex’s unique properties have also found a place in medical devices and industrial applications, where its combination of waterproofing, breathability, and toughness makes it highly valuable. Still, it’s the outdoor industry where Gore-Tex truly shines – trusted by adventurers to keep them dry and comfortable in the harshest weather.
Gore-Tex vs Gore-Tex Pro: Key Differences
Although both use the same Gore-Tex membrane technology, they’re optimised for different environments.
1. Durability
-
Gore-Tex: Designed for everyday use. Lightweight and flexible, but can wear faster under extreme or prolonged use.
-
Gore-Tex Pro: Built with heavier-weight fabric and more robust construction. Ideal for mountaineering, ski touring, and expedition-level conditions.
2. Breathability
-
Gore-Tex: Excellent breathability for moderate activity levels.
-
Gore-Tex Pro: Features larger pore structures and more open construction for even greater airflow – perfect for high-output activities like alpine climbing.
3. Water Resistance
-
Both are fully waterproof, but Gore-Tex Pro typically has a higher hydrostatic head rating and superior long-term water resistance, making it better for sustained exposure to rain, snow, or ice.
4. Cost
-
Gore-Tex Pro commands a premium price.
-
Regular Gore-Tex is more affordable and still delivers excellent performance for most users.
In short: Gore-Tex Pro is the more specialised option, while Gore-Tex hits the sweet spot for most outdoor enthusiast
The degree of breathability that the two textiles offer is another distinction between them. Because of its excellent permeability, Gore-Tex is well known for regulating body temperature and preventing overheating during moderate levels of exertion. The even increased breathability of Gore-Tex Pro, on the other hand, makes it perfect for high-intensity activities that produce a lot of heat and perspiration.
Both Gore-Tex and Gore-Tex Pro use a similar waterproofing technology known as “Gore-Tex membrane.” Millions of microscopic pores that are too big for vapour molecules to leave but too small for water droplets to pass through make up this membrane. This keeps out rain and snow while allowing sweat and moisture to escape from the interior of the garment.
Overall, the type of activity that Gore-Tex and Gore-Tex Pro are intended for is the primary distinction between them. Unlike Gore-Tex Pro, which is more specialised and designed for high-intensity sports that demand a higher level of durability and breathability, Gore-Tex is a trustworthy fabric that is ideal for a variety of outdoor activities.
Understanding Breathability Testing
Breathability is typically measured in grams of water vapour transmitted per square metre over 24 hours (g/m²/24h).
Testing involves:
-
Draping fabric over a chamber with controlled temperature and humidity.
-
Measuring how much vapour passes through over time.
-
Repeating the test in various conditions to get a complete performance profile.
Standard testing methods include:
-
The Sweating Guarded Hot Plate
-
The Sweating Thermal Manikin
These are standardised by organisations such as American Society for Testing and Materials (ASTM) and British Standards Institution (BSI).
Real-world breathability, however, also depends on environmental factors (temperature and humidity), activity intensity, and garment design. So while lab numbers help compare fabrics, field performance can vary.
How Waterproof Ratings Are Measured
The water resistance of a fabric is usually measured by the amount of water pressure it can withstand before it starts to leak. This is expressed in millimetres (mm) of water column pressure.
The testing process is fairly straightforward:
-
The fabric is placed over a small chamber fitted with a calibrated pressure sensor.
-
Water pressure is gradually increased.
-
The exact point where water begins to seep through is recorded as the fabric’s waterproof rating.
-
To ensure consistency, this process is repeated multiple times.
The two most common testing methods are the Hydrostatic Head and the Spray Test, both of which have been standardised by organisations like the American Society for Testing and Materials (ASTM) and the British Standards Institution (BSI).
It’s important to remember that real-world performance can vary. A fabric’s water resistance can be influenced by factors like:
-
The surface tension of the water
-
The size and shape of droplets
-
The porosity and texture of the fabric itself
Because of these variables, hydrostatic head ratings are best used as a comparison tool, not an absolute measure of how a fabric will behave in the field.
Gore-Tex vs Gore-Tex Pro in Wet Conditions
Both Gore-Tex and Gore-Tex Pro score well above standard waterproof benchmarks. However, Gore-Tex Pro is designed to perform better in sustained wet weather or under high-pressure conditions (like sitting on wet snow or kneeling in mud for long periods).
-
Gore-Tex: Versatile and reliable for general outdoor use.
-
Gore-Tex Pro: Built for serious adventurers who need maximum protection in harsh, prolonged conditions.
While Gore-Tex Pro comes at a higher price, its enhanced durability, breathability, and water resistance make it the go-to for demanding missions. For most casual users, however, standard Gore-Tex still offers outstanding performance and comfort.
Conclusion
Both Gore-Tex and Gore-Tex Pro excel at what they do – keeping you dry, comfortable, and protected in the outdoors.
-
Gore-Tex offers versatility and reliable waterproofing for most activities.
-
Gore-Tex Pro ups the ante with enhanced durability, breathability, and protection for serious missions.
