What Is GORE-TEX®
Welcome to our Expert Guide on GORE-TEX - as one of the most common outdoors searches on google, there is a lot of curiosity about this product, such as ‘what is gore tex made of?’, ‘what does gore tex mean?’, ‘how does goretex work?’, ‘how long does gore tex last?’, ‘does gore tex wear out?’ and (don’t laugh) ‘is gortex waterproof?’.
What is GORE-TEX®?
A simple way to define GORE-TEX is it’s a premium windproof, breathable and waterproof material found in outdoor apparel, including snow gear, rain shells, winter jackets, footwear and accessories. So calling it gore tex fabric is not strictly accurate - it’s more of a fabric layer, and gore tex clothing is apparel that features gore tex material.
GORE-TEX’s microporous membrane’s impressive ability to keep water out while allowing sweat vapour to pass through makes it one of the most sought-after waterproof-breathable materials available.
What Is GORE-TEX® Made Of?
GORE-TEX is made by heating and cooling a combination of materials that are exposed to a reaction agent. The process creates PTFE, a Teflon-like material, that’s then stretched and bonded with polymers to create ePTFE, a durable and thin waterproof material that is laminated to a fabric’s outer layer.
The resulting GORE-TEX membrane is then sewn into the outermost layer of a garment. It’s most commonly integrated into apparel using 2-layer or 3-layer construction.
2-layer construction features GORE-TEX laminated to a face fabric and combined with a non-laminated lining layer such as mesh, nylon or microfiber. GORE-TEX 2L is generally warmer and heavier.
3-layer construction involves laminating all three layers together – the GORE-TEX membrane, face fabric and knit lining. GORE-TEX 3L is your classic uninsulated high-performance shell; more durable and lighter than the 2L construction.
GORE-TEX® vs. GORE-TEX® Infinium™
Is GORE-TEX waterproof? Is GORE-TEX breathable? The answer depends on the type of GORE-TEX technology. The brand offers products in two different categories:
- Products in the original GORE-TEX line-up are windproof, breathable and waterproof, designed for high-performance in wet conditions.
- PProducts in the GORE-TEX Infinium line-up are intended for use in drier weather, offering protection from the wind and cold, and is water-resistant but not waterproof.
GORE-TEX® Waterproof Ratings & Breathability
A fabric’s waterproofness is measured in a lab using a hydrostatic head test. This test determines how many millimetres of water a fabric can withstand in a 24-hour period before seeping through. This is why waterproof ratings are given in ‘mm’ units.
- Waterproof ratings range from below 5,000mm to above 25,000mm.
- The higher the number, the more waterproof the fabric is.
- Anything with a rating above 25,000mm is considered completely waterproof.
Breathability is defined as the amount of water vapour (i.e. sweat) that can be let out through a fabric. Breathability is important for staying dry during high output activities. Breathability ratings are assigned according to the amount of moisture that can pass through a square metre of fabric in a 24-hour period.
- Breathability ratings range from below 10,000g/m2/24hrs (10K) to above 30,000g/m2/24hrs (30K).
- The higher the number, the more breathable a fabric is.
- 5K-20K is a solid breathability rating while products with ratings in the 20-30K range are considered high-performance.
| TECHNOLOGY | WATERPROOF RATING | BREATHABILITY RATING |
| GORE-TEX | Above 28,000mm | 17K |
| GORE C-KNIT | Above 28,000mm | 20K |
| GORE-TEX Pro | Above 28,000mm | 25K |
| GORE-TEX Active | Above 28,000mm | Above 25K |
| GORE-TEX Paclite | Above 28,000mm | 15K |
Is GORE-TEX® Warm?
GORE-TEX helps you stay warm in wet weather conditions by keeping you dry – your body loses heat more quickly when you’re wet. GORE-TEX is not an insulating layer on its own, but serves as an outer shell to protect the insulating layers you wear beneath it.
Types of GORE-TEX®
| GORE-TEX® |
Most Versatile Used in 2-layer and 3-layer constructions, the original GORE-TEX membrane can be integrated into apparel designed for any activity. The classic 3-layer membrane features GORE-TEX sandwiched between a PU coating and an outer fabric. |
| GORE® C-KNIT™ |
Most Comfortable C-KNIT is a type of stretchy fabric backer integrated into GORE-TEX membranes, designed to make products lighter, softer and more breathable. |
| GORE-TEX® Pro™ |
Most Durable No PU coating, which increases the membrane’s overall performance. The GORE-TEX Pro membrane features Micro Grid backer fabric, which provides increased abrasion resistance. |
| GORE-TEX® Active™ |
Most Breathable This 3-layer membrane is thinner and lighter, making it less durable than the classic GORE-TEX or GORE-TEX Pro membranes. The lining fabric is incorporated into the PU coating, which increases its breathability. |
| GORE-TEX® PacLite™ |
Most Packable GORE-TEX garments featuring PacLite technology are designed to be lightweight and super packable. However, they’re less durable than classic GORE-TEX or GORE-TEX Pro membranes. |
| GORE-TEX® Infinium™ |
Most Windproof GORE-TEX Infinium products offer the most breathability and wind protection but they aren’t waterproof. Infinium garments are best utilized as mid or outer layers. |

The GORE-TEX Story
Curiosity about who owns gore tex, when was gore tex invented and who invented gore tex is understandable given how famous it is. Gore-Tex was co-invented by Wilbert L. Gore and Gore's son, Robert W. Gore in 1969, and the company they founded, W. L. Gore & Associates, still owns the product.
How to care GORE-TEX?
If you’re wondering how long does gore tex last, or does gore tex wear out, that’s a good question that has a lot to do with how you look after it. Technically it doesn’t “wear out” but the membrane is fragile, so excessive abrasion of the bonded fabric can lead to the waterproofing to fail. Another tip is if you waterproof spray gore tex garments with a DWR fabric treatment, you can enhance the outer fabric’s water repellency, which in turn enhances the breathability of the garment.
GORE-TEX VS Waterproof Competitors?
With other cheaper waterproof membranes on the market, you could ask, is gore tex worth it? Choosing apparel or accessories with the GORE-TEX label is a sure way to ensure the consistent quality and performance you expect from an industry-leading brand name.
