What Is GORE-TEX®
GORE-TEX is a popular type of windproof, breathable and waterproof material found in outdoor apparel, including snow gear, rain shells, winter jackets, footwear and accessories.
GORE-TEX’s microporous membrane’s impressive ability to keep water out while allowing sweat vapor to pass through makes it one of the most premium 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? 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.
- Products 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 millimeters 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 vapor (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 meter 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. |
