Simms was built on the pillars of innovation. Founded in 1980, it was the brainchild of John Simms who saw the need to develop high quality waders for the dedicated fly fisherman. Utilising the technological advances in fabrics, Simms introduced the first pair of breathable waders with highly advanced GORE-TEX® fabrics. Today they continue to evolve the brand & its high quality fishing clothing working from their new factory in Bozeman, Montana.
