SIMMS Fishing – American Fishing Heritage Since 1980

The story of SIMMS Fishing began in 1980 with John Simms, an enthusiastic angler and inventor who was constantly looking for practical ways to improve fishing equipment. One of his early products was a neoprene gravel guard designed to keep small stones and debris from entering wading boots.

These first innovations gradually led the company towards the development of specialised wading equipment. A decisive moment came in 1993, when K. C. Walsh acquired SIMMS Fishing Products and moved the business to Bozeman, Montana.

That same year, SIMMS introduced its first breathable fishing waders made with GORE-TEX technology. This represented a significant step forward from traditional rubber and neoprene waders. While earlier materials tended to trap moisture and body heat, the new breathable membrane allowed water vapour to escape while preventing external water from entering.

Over the following decades, SIMMS continued to refine its materials, construction methods and product designs. What began with practical wading accessories developed into a specialised fishing equipment brand offering waders, footwear, waterproof outerwear, technical clothing and fishing accessories.

Bozeman, Montana – A Central Part of the SIMMS Identity

Bozeman has become an important part of the SIMMS story. The company maintains product development and manufacturing operations in Montana, where selected wader models continue to be produced.

Wader construction involves considerably more than selecting a waterproof fabric. Seam placement, fabric layers, neoprene stockingfoot attachment and the overall fit all influence comfort, mobility and durability during extended use.

SIMMS has worked on refining these details throughout its history. The introduction of the Guide Waders in 1995 marked an important improvement following the first generation of breathable waders. More puncture-resistant face fabrics, improved seam positioning and developments in stockingfoot construction helped address some of the challenges associated with the earliest designs.

Today, selected models such as the G3 Guide and G4Z are manufactured in Bozeman using imported GORE-TEX materials. This manufacturing distinction applies to specific wader lines rather than the entire SIMMS product range.

SIMMS Fishing Waders – GORE-TEX, Toray and Technical Construction

SIMMS fishing waders remain one of the manufacturer's core product categories. The range includes chest waders, waist-high models and designs with waterproof front zippers, providing different options for fishing conditions and personal preferences.

Selected models, including the G3 Guide and G4Z series, use waterproof and breathable GORE-TEX materials. Their construction is developed around keeping external water out while allowing moisture vapour to move away from the body.

However, not all SIMMS waders are made with GORE-TEX. The Freestone family uses four-layer Toray QuadraLam fabric, while Tributary waders feature waterproof and breathable polyester constructions.

Beyond the materials, SIMMS places particular emphasis on fit and movement. Anatomically designed stockingfeet, carefully positioned seams and different sizing options help accommodate the physical demands of walking, bending and moving through the water.

Choosing suitable waders involves considering where and how frequently you fish, the conditions you encounter and the amount of movement required. Breathability, durability, freedom of movement and correct sizing are all important factors in finding a comfortable setup.

SIMMS Wading Boots – Traction, Support and Sole Options

Alongside its waders, SIMMS develops a range of wading boots designed to support anglers moving across uneven riverbeds, gravel banks and other challenging surfaces.

Different models use rubber or felt outsoles, offering options for different environments and fishing preferences. Selected boots can also be fitted with additional studs or cleats to adapt traction to specific conditions.

SIMMS offers accessories such as HardBite Studs and Star Cleats for compatible footwear. These components are designed to work with particular outsole constructions, so choosing the correct combination is important. Local restrictions on felt soles or metal studs should also be considered.

Fit is equally important. Stockingfoot waders require boots that provide enough room for the neoprene feet while maintaining adequate support and comfort. Boot construction, lacing systems and outsole characteristics all contribute to finding suitable footwear for regular use.

SIMMS Wading Jackets and Technical Fishing Clothing

SIMMS has expanded its expertise in waterproof materials beyond waders to develop a broad range of wading jackets, rainwear, insulating layers and technical fishing apparel.

Different garments are designed around different needs. Selected waterproof jackets use breathable membrane technologies, including GORE-TEX in appropriately equipped models. Other clothing focuses on warmth, wind resistance or comfort during active fishing in warmer conditions.

For wading jackets, practical features can make a noticeable difference. Higher-positioned pockets remain more accessible while wading, adjustable cuffs help limit water entry, and a suitable fit allows freedom of movement when casting.

Layering is another important part of dressing for changing conditions. Breathable waders provide protection against external water, but suitable insulating clothing is still needed when fishing in colder temperatures.

Beyond waterproof outerwear, the SIMMS range includes fishing vests, technical shirts, trousers, caps, packs, bags and accessories designed to help anglers organise and carry essential equipment.

Wader Care and Repair – Extending the Life of Fishing Equipment

SIMMS also provides guidance on maintaining and repairing technical fishing equipment. Regular cleaning, correct drying and checking for damage are important parts of caring for breathable waders and waterproof clothing.

Removing dirt and residue after fishing, following the garment's care instructions and allowing equipment to dry properly can help preserve its intended performance. Seams, stockingfeet and other areas exposed to frequent wear should also be checked periodically.

The manufacturer provides repair services for eligible products, alongside information on identifying and addressing certain types of damage. Warranty and repair arrangements vary by region. For equipment purchased outside the United States and Canada, SIMMS advises customers to consult their authorised dealer or distributor regarding the applicable conditions.
