THE GORE-TEX MEMBRANE IS THE HEART OF ALL GORE-TEX PRODUCTS
The GORE-TEX membrane contains 9 billion microscopic pores per square inch. These pores are so small that water droplets cannot get through but water vapor can still escape. Water from the outside cannot penetrate and cold winds cannot pass through, but perspiration can escape easily, keeping you dry and comfortable all day. GORE-TEX fabrics are created by integrating the GORE-TEX membrane between an outer fabric and lining.
GORE-TEX PRO SHELL
This Gore fabric is waterproof, exceptionally lightweight and offers the ultimate in breathability, durability and extended comfort. Constructed with a woven backer, GORE-TEX Pro Shell garments slide easily over other layers and offer exceptional tear strength and internal abrasion-resistance.
GORE-TEX PRO STRETCH
For the ultimate in mobility and comfort, stretch panels are built into the crotch and underarm gussets for waterproof, breathable protection that won’t slow you down.
GORE-TEX PACLITE® PLUS
These garments use a 2-layer unlined construction. The GORE-TEX membrane is laminated to an abrasion resistant outer face textile, assuring durable protection. A new abrasion resistant treatment of the inner surface makes a separate lining unnecessary. This makes them thin, light, and highly packable—while being all durably waterproof, windproof, and extremely breathable.
Non-waterproof GORE-TEX INFINIUM™ products range builds on the quality and performance of the original GORE-TEX products range. It is not a technology on its own but hosts a variety of established and new product technologies that provide you with versatile aspects of comfort and protection. Whatever passions keep you moving, the new GORE-TEX INFINIUM™ series has best in class solutions. Made for when comfort and performance take priority over waterproofness.
Whether you’re a seasoned guide or a kid taking her first cast from the family dock. Whether your home waters are Tokyo Bay or Bristol Bay. Whether you pull a drift boat or tournament-ready rig, Simms is committed to lowering the barriers that stand between the world’s rivers, lakes and open waters and those who hear their call. Because we’ve seen with our own eyes the power our sport has to unite people, relieve stress, develop character, restore watersheds and ease personal suffering. Which is why we believe the more people who pick up a rod and take a cast, the better off we’ll all be.
JOHN SIMMS, VISIONARY GUIDE
Simms was founded in 1980 by visionary angler and longtime river guide John Simms. Having spent decades providing clients with life-changing experiences on the world’s most majestic rivers, John realized the waders available at that time weren’t up to the job of keeping the folks he was guiding dry, comfortable and safe on the river. Never mind the guides who, as he did, lived and breathed the sport 150+ days a year. So, he set about creating products worthy of a new generation of anglers who, like him, wanted to get out on the water earlier and stay out longer in any weather.
By the late 80's, John had put his namesake products on the map as the most rugged and dependable waders in the sport. Having set the company on the right path, he was ready to spend more time on the rivers he loved. After all, it was the reason he built those waders in the first place. At the same time, he wanted to ensure Simms would continue to craft the type of high-quality products the brand had become known for and anglers had come to depend on.
K.C. WALSH, REMAKING AN INDUSTRY
In 1993 K.C. Walsh, a lifelong angler raised in a multi-generational fishing family, combined two of his passions, fishing and guiding companies to realize their full potential. K.C. had spent his career helping companies grow and flourish as a management consultant. With K.C.’s rare combination of devotion to the sport and deep management experience, those close to the deal knew Simms would thrive. And thrive it has. In the almost 25 years under K.C.’s leadership, the quality of Simms products has continued to improve, the workforce has continued to grow and the product line has continued to expand.
K.C.’s first order of business back in 1993 was to move Simms' Headquarters to Bozeman, Montana. Relocating to Bozeman put Simms a stone’s throw from some of the most legendary fishing rivers in the world. And where there’s great fishing, there are great fishermen. Simms taps into the experience of these expert anglers, employing them at every level and in every role, from designers, developers and product managers, to wear testers, consultants and craftspeople.
GORE-TEX® WADERS MADE IN BOZEMAN, MONTANA
That first year also saw the release of Simms’ first-ever waterproof, breathable wader featuring GORETEX® construction. The wader was a groundbreaking success and would prove to be the beginning of a long and productive partnership between Simms and W.L. Gore & Associates. Since then, Simms has become known as a place the fishing industry looks for the latest advances in GORE-TEX technology.
In 2012, Simms expanded its presence in Bozeman with a new 60,000 square-foot facility housing its corporate headquarters and wader production facility. The expansion has provided elbow room to drive product development, solidified Simms as the sole fishing wader manufacturer in the USA and showcases our unwavering commitment to high quality, U.S.-based manufacturing. Today, Simms is recognized as a global leader in the fishing industry and employs more than 180+ at its Bozeman headquarters.
