    or in the words of a navy seal testing gore-tex gear "this is good sh**"

    A conversation with former Navy SEAL Master Chief Scott Williams and former Gore Associate Wayne Von Stetton.

    The legacy of W.L. Gore & Associates (Gore) providing protective and comfortable clothing systems to the US Army goes back more than four decades. Already in 1978, the "Rainwear Division" of Gore first provided a sample of GORE-TEX laminate to the US Army Lab at Natick (currently known as DEVCOM or the Combat Capabilities Development Command — Soldier Center) but it did not gain much traction. Four years later, Wayne Von Stetten joined Gore and, early in his career, founder and CEO Bill Gore, came to Wayne and asked him to explore the military market in the US. At the time, Bill's grandson was serving in the military, and Bill believed they could benefit from improved clothing.

    No wonder as at that time most of the cold weather clothing the US Army was using, went back to the technology of what was worn in the Korean War, and they hadn't made many advances since then. In the early 1980's, many of the troops and warfighters were buying consumer gear from Marmot — the Mountain Parka in forest green color — or from companies like The North Face or Eddie Bauer with their own money, as it was assumed that the government would not pay the high prices for good weather protective gear. "The story was that the U.S. suffered more casualties to the elements and cold weather than they had lost in battle during the Korean War - not sure if that's true or not, but that's what was being said at the time", says Wayne.

    "Another event that gave GORE-TEX products a boost was the Falkland Island War between the UK and Argentina over British dependent territories in the South Atlantic. Argentina invaded and occupied the Falkland Islands and the British defended and ultimately regained their territory", reports Wayne. "Many of the Royal Marines, SAS, and British Army were wearing or testing GORE-TEX products at the time and gave it a huge endorsement over their conventional gear", he continues.

    The British troops were raving about the performance of the GORE-TEX gear in the field. They also attested to the increased efficiency and focus of the troops thanks to their level of comfort. In 1983, the U.S. Government agreed to fund a 3-year development program code-named ECWCS (Extended Cold-Weather Clothing System) and a year later, three different service branches tested GORE-TEX sample products: the USMC 3rd MEF (Marine Expeditionary Force) at the Marine Corps Mountain Warfare Training Center, Pick Meadows, Bridgeport, CA; the NSW SEAL teams 2, 4, 6 (East Coast); and the US Army 10th Mountain Group — Ft. Drum, NY and in Italy. Scott Williams, former Navy SEAL Team 2 Master Chief, was an earlier tester for the GORE-TEX gear.

    In the winter of 1984, trials in Alaska and at Fort Ethan Allen in Vermont were successful, achieving an operational capability at -40 degrees Fahrenheit. The next year one thousand U.S. marines participated in a NATO European invasion exercise in Norway without a single cold weather casualty, a first for the U.S. Marine Corps. The positive test feedback from Marines, SEALS and Mountain groups as well as the experience made by the British Armed Forces led to the initial order for about 10,0000 yards to develop the first ECWCS Parka in 1985/1986 together with a military garment contractor, Tennessee Apparel.

    Mid 1990s - ecwcs generation ii - waterproof by design

    Then in 1988, the first major order for general use resulted in 250,000 sets and ECWCS became the uniform of choice. The system became so popular that the demand exceeded the Army's initial five fielding plan, so the government allowed Gore to GORE-TEX ECWCS gear through the Military Exchange Stores. In the same year, Gore Associates were challenged to test the gear themselves. So, a team of military sales Associates from the UK, Germany, Sweden, France and Italy took a trip north of the arctic circle in Sweden and spent three days and nights marching and sleeping outside, putting the products to the test limits. "That allowed us to test the product to prove 'We've used it, we tested it'. When talking to military personnel, we were able to say that we tested the gear, and not repeat what we read in a book or letter", says Wayne.

    In 1991 at the AUSA trade show, Army Chief of Staff, General Gordon Sullivan, stopped by Gore's booth and spoke with a young Product Specialist, Terri Kelly (who, by the way, became CEO of Gore in the mid-2000s) about GORE-TEX parkas leaking. Just a couple of years later, winter of 1993, Scott Williams was sitting in a ski lift in Alaska along with his Commanding officer. Both wearing GORE-TEX gear, but only one — Scott — was comfortable and dry as he was wearing a Marmot Alpinist jacket whereas his skipper's gear was not, and the reason was a poorly designed military garment at the time. "I realized the importance of design. Even if you have the best material in the world, it needs to be built right, and so we worked with the outdoor company Patagonia to design PCU Level 6 so it was storm certified", confirmed Scott Williams.

    "The feedback from General Sullivan and experience made by the SEAL team, led to the development of garments that were also waterproof by design/fit-for-use with flaps over and under the zipper and other leakage areas. Eventually, it led to a new improved design that became a Generation II of ECWCS in the early mid-1990s", Wayne explains.

    A key requirement for developing the second generation of ECWCS was to lighten the load of the soldiers, allowing the to get four hours of uninterrupted sleep without getting wet. From the mid-90s onwards, full special operations acted with rapid movements and rapid strike activities. Special Operation warfare concentrated on fast movement and rapid mission achievement. Being cold or wet can be a major distraction so staying dry and comfortable allowed SOF Operators to focus on the mission at hand "The command was 'get in and out fast'", explains Wayne. He continues: "From 1982-2003, Gore focused on expansion into other markets - firefighting, law enforcement, workwear, etc. - but there was not a lot of new product development in the military but then Gore stood up and developed new, higher performing and lighter material."

    2003/2004 ecwcs generation iii - introducing a multi-layer system

    The third generation ECWCS was developed as a multi-layered system. Initially, the SOCOM Program Office at NATICK started developing a multi-layered system based on products used in outdoor adventure sports (Alpinist, Skiing, Hunting, etc.). The challenge was to develop a multi-layer system that could be interchangeable based on the weather conditions and work activity level. The idea was to keep the body dry both from the outside elements but also on the skin. They required wicking base layers and breathable outer layers. SOCOM developed the Protective Combat Uniform (PCU) based input from outdoor enthusiasts like Mark Twight and high-end consumer outerwear brands (Patagonia, TNF, Marmot, etc.). Level 6 on the PCU was a cold, wet weather layer which incorporated a 2-Layer GORE-TEX laminate. In 2004, based on the PCU, the US Army was hesitant to update to a 3rd generation due to cost but, there were some instrumental stakeholders that helped push through the need for correct design. The Army quickly adopted the concept and developed a very similar 7-layer system called GEN III ECWCS but in Army camouflage and some other slight modifications.

    ECWCS Generation IV

    After providing protection and comfort through GORE-TEX defense products to the US Army, US Air Force, US Navy, US Marines and SOCOM for more than 40 years, it is now time for the next generation of ECWCS taking into account all the learnings, feedback and input from decades of hard innovative work, both in the labs and in the field. At this year's AUSA show, Gore will be presenting system ideas and innovative technologies around the next generation All Weather Clothing System.

    "This is good sh.."

    Looking back all those years, Scott and Wayne summarize their experience with GORE-TEX products. Scott: "Even though you can have the best materials in the world, it still has to be built correctly, that is one of my main takeaways in working with Gore." Wayne adds, "Ultimately, we were able to reduce the number of people who died from environmental casualties. ECWCS gave greater capabilities to operate for longer. Soldiers referred to GORE-TEX as a 'force multiplier' which means making 10 soldiers worth 15, as they were able to carry more, and had better protection for their hands and feet as well (the use of GORE-TEX footwear and gloves grew significantly in those years). It's about extending the range, how long they can go and operate." I asked Wayne if he remembers a quote from a user when testing the GORE-TEX garments. "During an extensive test in cold and wet environment, I asked a solder 'How do you like GORE-TEX gear?' and his response was 'This is good sh**!", remembers Wayne.

    Gore Announces NFPA 1994, Class 3R Certified Suit
    Highly Breathable Protection in Contaminated Environments

    ELKTON, Md. (May 29, 2018) – W. L. Gore & Associates’ Protective Fabrics Division has expanded its line of certified products for emergency responders with the addition of the Ruggedized Class 3 suit made of GORE® CHEMPAK® selectively permeable fabric. Manufactured and distributed by Blauer® Manufacturing Company, Inc., the Ruggedized Class 3 suit is certified to NFPA1994, Class 3R and NFPA 1992 Standards (2018 Edition). The suit’s ruggedized construction makes it ideal for extended CBRN responses that include tactical entry or search & rescue missions for several reasons.

    First, the GORE® CHEMPAK® selective permeable fabric is engineered to deliver extremely durable protection against potential exposure to liquid and vapor chemicals, biological, and radiological particulates, blood and body fluids, and emerging pharmaceuticals such as fentanyl — even after exposure to field contaminants such as seawater, sweat, and hydraulic fluid.

    Second, the form-fitting garment, with reinforced padding at critical stress points for a greater level of cut and puncture resistance, is designed to enable the responder to move more easily and effectively throughout hazardous surroundings, confined spaces, and rubble piles.

    Third, the highly breathable GORE® CHEMPAK® selectively permeable fabric enables the responder to stay actively involved in the mission significantly longer than an impermeable suit does. While maintaining a minimum of four hours of permeation protection, Gore’s barrier enables sweat vapor to escape through the suit, which helps reduce heat stress.

    And finally, the NFPA certifications and AEL/SEL qualifications of the Ruggedized Class 3 suit make it eligible for grant funding.

    According to Jason Horowitz, Gore’s North American Chem-Bio product manager, their team works closely with end users to identify their needs when developing a new product. CBRN responders had described the challenges of needing protection in harsh surroundings combined with the capability of operating in temperature and humidity extremes. He explained, “The new garment needed to be durable enough to withstand rigorous use associated with tactical entry or search and rescue operations, providing a greater level of cut and puncture resistance than the current Class 3 ensembles. It also needed to provide increased visibility, range of motion, and dexterity, while optimizing the integration of helmets and ballistic vests. We’re really excited about offering this new level of durability in a certified Class 3R garment.”

    GORE® PYRAD™ Flame Retardant technology offers thermal / flashover burn protection for traditional textiles

    ELKTON, MARYLAND, OCTOBER 10, 2011 – W. L. Gore & Associates, Inc., announces the commercial introduction of GORE® PYRAD™ Flame Retardant technology, a new laminate technology that offers an optimal combination of thermal / flashover burn protection, environmental protection, and comfort. GORE® PYRAD™ Flame Retardant is a durably bonded laminate solution that allows manufacturers to integrate Flame Retardant (FR) performance into protective outerwear where traditional (non-FR) textiles, such as nylon and polyester, are used.

    GORE® PYRAD™ Flame Retardant offers highly efficient thermal protection per unit weight and demonstrates excellent flame and burn performance in Pyroman (ASTM F 1930) testing, and retains this feature, even after contamination of fuels, oils and lubricants. Garments made with GORE® PYRAD™ Flame Retardant also exhibit best-in-class mechanical integrity after flashover exposure with very low shrinkage and no break-open.

    GORE® PYRAD™ Flame Retardant, when used in conjunction with nylon and polyester face fabrics (which are abrasion and pilling resistant), ensures durability and comfort while adding very little in terms of weight and water pickup. GORE® PYRAD™ Flame Retardant can be constructed with a wide range of fabric options in a variety of camouflage prints and colors that are notably more colorfast to light and laundry (than most traditional FR face textiles).

    The first commercial applications incorporating GORE® PYRAD™ Flame Retardant are military outerwear and workwear such as in-weather protective clothing for oil & gas use. The technology is also currently being evaluated for use in handwear, footwear, tents/shelters and other applications, where fire retardation is essential.

    Garments constructed with GORE® PYRAD™ Flame Retardant will be displayed at AUSA, Washington D.C., from October 10-12 at booth # 3319 and at the Safety, Security, and Health at Work International Trade Fair with Congress, Dusseldorf, Germany, from October 18-21 in Hall 04 booth # C05.

    Gore Expands Portfolio of Breathable ChemBio Fabrics

    Elkton, Maryland, July 29, 2008 - W. L. Gore & Associates announces that their breathable GORE® CHEMPAK® Selectively Permeable Fabric is the first and only breathable CBRN barrier component-recognized to the NFPA 1994 [2007 Edition] Class 3 standard. Tactical users can now benefit from comfortable CB protection because this fabric is available in the Blauer WZ9430 Major Incident Response Team suit, which is part of the first breathable, certified NFPA 1994 Class 3 protective ensemble. Having recently announced the first and only breathable CBRN barrier that is component-recognized to NFPA 1971 [2007 Edition] standard CB option, Gore continues to demonstrate its leadership in providing breathable protective barriers for ChemBio personal protective equipment (PPE).

    GORE® CHEMPAK® Selectively Permeable Fabric is both liquid-proof and air-impermeable, which provides protection for the user against liquid, aerosol, and vapor TICs and CWAs. At the same time, this barrier fabric improves total heat loss by allowing moisture vapor from perspiration to escape from the garment, thereby reducing heat stress and increasing comfort. These characteristics allow first responders wearing suits made with Gore's fabric to stay active on duty for longer periods of time without compromising their safety. In addition to this, the fabric is constructed with a unique, intrinsically stable, non-carbon-based laminate, giving it a longer service life and ensuring lasting protection that end-users expect when using Gore products.

    Gore has a long-standing tradition of not only creating outstanding products but developing these products with the end-user in mind. As Joe Staudenmayer, a CB-focused product specialist at Gore, says, "Gore's long-term commitment in developing ChemBio applications for our products is now coming to fruition. We engineer all of our products to meet the specific needs of the end-user, a philosophy we call 'fitness for use.' With this approach in mind, we developed GORE® CHEMPAK® Selectively Permeable Fabric and tailored it to meet various military and emergency response CB requirements such as NFPA 1971 CB option and NFPA 1994, Class 3. By drawing on our expertise in protective barriers and then collaborating with those who use our products, we were able to customize our fabric to meet the demands of responders in various situations."

    This new fabric is the latest addition to Gore's line of protective fabrics for emergency responders, which also includes GORE® CHEMPAK® Ultra Barrier Fabric used in a variety of protective ensembles as well as CROSSTECH® Moisture Barriers used in garments, footwear, and gloves for fire, EMS, technical rescue, and law enforcement.

    GORE® CHEMPAK® Selectively Permeable Fabric Selected for Another CBRN Suit

    Elkton, Maryland, March 24, 2009 – W. L. Gore & Associates announces that its breathable GORE® CHEMPAK® Selectively Permeable Fabric has been selected as the chemical barrier for the NFPA certified WZ9435 XRT Response Suit made by Blauer Manufacturing Company. This easily donned, single-piece coverall, which does not require taping, allows law enforcement professionals to respond more quickly and remain deployed for up to eight hours. As the first and only breathable CBRN barrier that is component-recognized to the NFPA 1994 [2007 Edition] Class 3 standard, Gore’s fabric provides protection against NFPA-identified hazards plus additional toxic industrial chemicals (TICs) and chemical warfare agents (CWAs). By combining this level of protection with its unique membrane technology, Gore continues to lead the industry in developing breathable, protective barriers for ChemBio personal protective equipment (PPE).

    This latest fabric from Gore provides breathability not found in other liquid-proof ChemBio garments. By allowing moisture vapor from perspiration to escape from the garment, this fabric reduces heat stress and increases comfort allowing the wearer to remain engaged for up to eight hours without compromising their safety.

    This fabric also gives added confidence because of its durable construction. Gore’s proprietary barrier membrane is bonded between an outer fabric and an inner liner to provide protection even during rigorous physical activities. In addition, testing indicated that this fabric provides cumulative breakthrough protection against the NFPA 1994, Class 3 chemicals plus additional liquid CWAs and gas TICs.

    The new XRT suit is a single-mission coverall that can be donned and doffed multiple times in the event of false alarms. Because Gore engineered this fabric with an intrinsically stable, non-carbon-based membrane that does not adsorb chemicals or degrade over time, suits made with GORE® CHEMPAK® Selectively Permeable Fabric have a longer out-of-bag service life than carbon-based suits.

    Gore has a long-standing commitment to developing high-quality products that meet the specific needs of the user. As Steve Lampo, a ChemBio product specialist at Gore, explains, “We have been developing breathable, protective barriers for almost 30 years; and before engineering a new barrier, we work closely with each user community to identify the crucial factors that affect its protective clothing. Taking this approach, we have tailored our ChemBio fabrics to meet various military, law enforcement, and emergency response CB requirements. For Blauer’s WZ9435 XRT Response Suit, we knew that, in addition to protection against potential exposure to TICs and CWAs, breathability was essential so that responders could remain engaged for hours rather than minutes.”

    This selectively permeable fabric is the latest addition to Gore’s line of protective fabrics for emergency responders, which also includes GORE® CHEMPAK® Ultra Barrier Fabric used in a variety of CBRN protective ensembles as well as CROSSTECH® Fabric used in garments, footwear, and gloves for fire, EMS, technical rescue, and law enforcement. For more information about this latest suit made with one of Gore’s ChemBio fabrics, call 800.431.GORE or visit GoreChempak.com\XRT.
