Good alternatives to GORE-TEX are also available, such as FUTURELIGHT™ from The North Face, Pertex Shield, and less expensive PU film fabrics like Patagonia's H2No.

GORE-TEX. Gore-Tex® is not a fabric, but a lightweight, windproof, waterproof and yet breathable membrane that allows water vapour to pass through. This make Gore-Tex® especially well-suited to outdoor and walking shoes. This synthetic and therefore vegan material was originally patented by Robert W.

Therefore, it is not a PFC of Environmental Concern and it does not degrade into them. “Gore continuously strives to deliver outdoor products with the optimal combination of high technical performance and sustainability.

GORE-TEX® is the best-known branded membrane and is made using PTFE (polytetrafluoroethylene). ... The fluorochemical companies are now developing PTFE formulations that do not use PFOA in the manufacturing process.

One drawback of GORE-TEX is that you need to keep it clean to keep it waterproof—and clean it properly. Over time, as perspiration from your body escapes out through the material, it can cause a buildup of surfactants (detergent-like chemicals) that reduces the effectiveness of the waterproofing.Nov 17, 2020

The underlying technology of Gore-Tex is a membrane, made by stretching PTFE (Teflon) into a membrane, with pores 20,000 times smaller than a water droplet, but 700 times larger than a water molecule. ... This membrane is sandwiched between a durable outer “face” material, and a “backer” inner lining.Feb 19, 2021

Each square inch of the GORE-TEX membrane has nine billion pores. Each of these tiny holes is 20,000 times smaller than a water droplet. ... That's what we mean by breathable—and it's what makes products made with the GORE-TEX membrane so much more than just waterproof.Dec 3, 2019

The final reason Gore-Tex boots leak is because the Gore-Tex membrane itself is compromised in some way, either from footwear use and abuse which results in a puncture or small tear or because of manufacturer defect (the least likely cause).Apr 1, 2013

Good alternatives to GORE-TEX are also available, such as FUTURELIGHT™ from The North Face, Pertex Shield, and less expensive PU film fabrics like Patagonia's H2No.

GORE-TEX INFINIUM™ and GORE-TEX INFINIUM™ WINDSTOPPER® garments are designed to keep light rain and snow out. Which means that, yep, some GORE-TEX INFINIUM™ products are even water resistant.Nov 5, 2019

The new membrane is made without PFAS (per- and polyfluoroalkyl substances), but GORE-TEX^® items generally have a second waterproofing treatment, a surface coating known as durable water repellent (DWR) made of PFAS. The first products using this new PFAS-free membrane will be available for purchase in late 2022.Sep 30, 2021

• GORE-TEX is primarily used in outdoor apparel and sportswear, but this fabric is also commonly used in accessories like gloves and shoes. Less commonly, GORE-TEX may even be used in industrial and medical applications.

• To remain effective, GORE-TEX fabric must be treated regularly with durable water repellent (DWR), a toxic chemical spray that wears off over the course of a few years. While DWR is not necessary to keep GORE-TEX waterproof, this substance keeps water off the surface of GORE-TEX fabric, allowing breathability.

• GORE-TEX was featured in the space suits worn by astronauts during the first Space Shuttle missions, and in 1982, the first GORE-TEX footwear booties were developed. W.L. Gore started producing GORE-TEX gloves in 2003, and the GORE-TEX Pro line was introduced in 2006.

• The Gores had recently been performing experiments involving stretching heated rods of PTFE, and in a fit of frustration, Bob yanked at a rod instead of slowly stretching it. Much to his surprise, the rod stretched over 1000%, and it resulted in a highly porous material that was more than 70% air.

Gore-Tex was co-invented by Wilbert L. Gore and Gore's son, Robert W. Gore. In 1969, Bob Gore stretched heated rods of polytetrafluoroethylene (PTFE) and created expanded polytetrafluoroethylene (ePTFE).

Gore-Tex materials are typically based on thermo-mechanically expanded PTFE and other fluoropolymer products. They are used in a wide variety of applications such as high-performance fabrics, medical implants, filter media, insulation for wires and cables, gaskets, and sealants.

It is composed of stretched polytetrafluoroethylene (PTFE), which is more commonly known by the generic trademark Teflon. The material is formally known as the generic term expanded PTFE (ePTFE). Gore-Tex was co-invented by Wilbert L. Gore and Gore's son, Robert W. Gore.

There are close to a dozen different Gore-Tex fabrics in some form or another but here are the main ones used for waterproof clothing: Gore-Tex Pro – Used by professional outdoors people to endure heavy rain for sustained periods. This is the best of the best.
