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.
