Bozeman, Mont. – October 16, 2019 – For the past two decades, one arsenal of gear has traversed more country, explored more ecosystems, and endured more ungodly weather than any other fishing collection out there – Simms’ G4 Pro® Collection. Redesigned this year, the all-new collection is specifically designed for the world’s hardcore anglers who demand gear that allows them to fish longer no matter the terrain or conditions. The lineup includes the all-new G4 Pro® and G4Z® Stockingfoot Waders, the G4 Pro® Boot (available in Vibram® or Felt), and the G4 Pro® Jacket.

By utilizing the most technologically advanced materials available and cutting-edge design innovations, Simms’ new G4 Pro Collection sets the new standard in durability, performance, and fishing functionality. Collectively, this collection has endured over 20,000 hours of rigorous testing by a stable of Simms pros and ambassadors that guide in some of the world’s most unforgiving fishing locations.

“It’s our goal as a product development team to continue innovating and creating the best products for anglers,” said Bart Bonime, vice president, product design and merchandising for Simms. “The G4 Pro Collection represents everything we, at Simms, are about – design, innovation and passion. From making sure the product designs and material selections are top-notch to putting the products through the most rigorous testing, we know this collection is built to withstand the elements and last.”

The key ingredient to the all-new G4 Pro and G4Z Stockingfoot Waders is a new proprietary GORE-TEX® Pro Shell fabric. With 4-layers in the legs and seat for added durability and 3-layers in the upper for enhanced breathability, the new fabric package boasts the highest puncture, abrasion, and tear resistance ever from Simms. Both waders feature two innovations the fishing industry has never seen – a patented stockingfoot design and patented Sharkfin buckle. To offer an unmatched fit inside wading boots, Simms has incorporated all-new, patented, compression molded, anatomically correct left and right stockingfeet. The new stockingfoot design features raised panels on the forefoot as well as the ankle. When compressed, these panels greatly enhance fit which in turn, gives anglers significantly improved circulation for warmer feet in cold conditions. In addition, Simms has also included the patented Sharkfin Buckle a unique feature that provides a convenient spot for anglers to keep hemostats or mitten clamps out of the way, but close to hand.

Another new detail the product team brought to both new waders are super burly, low-profile, GORE-TEX belt loops to minimize line catch and increase overall durability. To offer comfort and support, both the new G4 Pro and G4Z Waders come equipped with adjustable, air-mesh suspenders and for an unhindered range of motion and durability, both waders are built with Simms’ patented front and back leg seams. On the G4 Pro, anglers can keep their hands warm with a zippered, reach-through, microfleece lined pocket and keep essential gear in easy reach with an oversized zippered, stretch-woven chest pocket, and the popular flip-out Tippet Tender. Anglers who prefer the waterproof center-front zipper design of the G4Z also have plenty of on body storage with two zippered, micro-fleece lined handwarmer pockets and two zippered stretch-woven chest pockets.

Long known to offer the best weather protection and tons of on-body storage, Simms has also completely revamped the G4 Pro Jacket. Constructed with extremely rugged 3-layer GORE-TEX Pro Shell fabric, the new G4 Pro Jacket offers the same amount of on-body storage delivered in a sleek and streamlined profile. Equipped with two large, fly box compatible, zippered chest pockets and a stash pocket on the sleeve, the jacket also features two zippered micro-fleece lined handwarmer pockets that give access to two rear game pockets. For even more storage and organization, anglers can take advantage of two stretch-woven, drop-in pockets as well as an interior, zippered stash pocket. For total foul-weather protection, the G4 Pro Jacket includes an oversized, 3-point adjustable storm hood with a high visibility accent as well as watertight shingle cuffs. Added features include a built-in sunglass chamois and a clever vertical flip-out fly patch that seamlessly tucks away when not in use.

For superior traction in challenging terrain and unrivaled friction in slippery rivers, Simms has released the burliest wading boot ever offered, the G4 Pro Boot. Built with an incredibly abrasion resistant synthetic textile mesh upper, the boot also features vacuum molded HF welded TPU film in high wear zones for added durability. For enhanced toe protection and support, the G4 Pro Boot features a three dimensionally molded rubber toe cap and heal clip. A fully neoprene lined closed cell foam interior prevents water absorption and adds next level comfort. Also aiding in comfort and stability is a dual density EVA midsole. Underfoot, the all-new G4 Pro Boot is powered by a Vibram Idrogrip rubber outsole to provide excellent friction on rugged terrain and outstanding slip resistance on slick river bottoms. For added stability in slippery streams, the Vibram outsoles incorporate 10 non-corrosive stainless-steel receptacles designed to lock in G4 Hardbite or G4 Alumibite Cleats, the greatest solution for cleat retention Simms has ever released. The G4 Pro Boot is also available with a 12mm studable felt outsole option.

Fishing is a passion and one that Simms takes great pride in – providing the best gear for all scenarios. Simms’ gear works as hard as you do and the all-new G4 Pro Collection was built to elevate every aspect of the angling experience, allowing the world’s most demanding fishing guides and anglers to conduct their work in the harshest terrain, weather, and conditions, with unmatched durability and reliability.
