The Simms G3 Guide™ Wading Jacket has long been the gold standard.

It’s the right choice for anglers who refuse to let a little (or a lot) of horizontal rain ruin a day on the water. The newest iteration isn’t just a minor facelift; it’s a refinement of what was already a top-tier piece of equipment. Here is a look at the features of the new G3 and how it actually performs when the weather turns south.

Overview: The Next Generation of Protection

The most notable shift in the new G3 is the move toward sustainability. The jacket now utilizes a 3-layer GORE-TEX®construction featuring a new ePE PFAS-free laminate and a C0 DWR (Durable Water Repellent). This means you get the same “Guaranteed to Keep You Dry” promise but with a significantly reduced chemical footprint.

• Advanced Shell Fabric: The face fabric is a rugged 70D 100% Recycled Nylon, paired with a smooth Nylon Tricot backer that slides easily over mid-layers.
• Cast-Back Construction: Rather than a standard stiff back panel, the G3 features a specific “Cast-Back” panel and articulated sleeves designed specifically to mimic the mechanics of a fly cast.
• Refined Storage: The jacket features two high-capacity chest pockets sized perfectly for medium fly boxes, alongside YKK® Aqua-Seal handpockets. These are self-draining and set slightly higher to accommodate deep wading.
• Visibility Features: The Limited Edition “Simms Orange” model includes a high-visibility orange stripe on the hood, designed to make you easily identifiable in gray-out conditions or emergency situations.
• The Shingled Cuff: Simms’ proprietary internal cinch watertight cuffs return, designed to create a seal that prevents water from traveling up your sleeve during a release.

In the Wild: Performance Review

Eco-Friendly Without Compromise

There is often a concern that “PFAS-free” gear won’t bead water as well as the old chemical-heavy versions. In the field, the new C0 DWR performs impressively. Rain beads and rolls off the 70D recycled nylon face just as effectively as its predecessors. At just 19 ounces, the jacket feels noticeably lighter and more “athletic” than G3s of the past, reducing fatigue during long days of hiking and high-repetition casting. We tested it during harsh spring conditions in Iceland and it kept me dry no matter how hard the rain came down.

Unrestricted Casting

The Cast-Back construction is where the G3 earns its “Guide” title. When you reach forward for a long mend or high-stick a nymph rig, you don’t feel the jacket pulling across your shoulder blades. The articulation in the sleeves means the hem doesn’t lift significantly when your arms are raised, keeping the seal around your waders intact.

Wading-Specific Utility

The length of the jacket is surgically precise. It hits just below the waist, which is the “sweet spot” for anglers. It’s short enough that you can wade waist-deep without the jacket becoming a submerged anchor, but long enough to provide full wind protection when you’re running a boat or wearing it with rain pants on deck.

The self-draining handpockets are a lifesaver. Because they sit higher on the torso, you can wade deeper while keeping your hands warm. If you do happen to dip the pockets, the self-draining design ensures you aren’t carrying a pound of river water around with you for the rest of the day.

Visibility and Safety

If you opt for the Limited Edition Simms Orange, the high-vis hood stripe is a standout safety feature. On big water or in heavy fog, it allows your fishing partner to keep an eye on your position from a distance. The 3-point adjustable storm hood also deserves praise—the brimmed design keeps rain off your glasses, and once cinched, it turns with your head so your peripheral vision isn’t blocked by a wall of fabric.

The Verdict

The 2026 Simms G3 Guide Jacket is a masterclass in refinement. By integrating recycled materials and PFAS-free technology into a package that is lighter and more mobile than ever, Simms has proven that “green” gear can still be “Guide” grade. It remains the definitive choice for the angler who needs a shell that can survive salt spray, alder thickets, and torrential downpours.

Pros:

• Significant weight savings (only 19oz).
• Eco-friendly ePE GORE-TEX and recycled face fabric.
• Superior “Cast-Back” mobility that eliminates binding.
• High-set, self-draining pockets ideal for deep wading.

Cons:

• Since the outer layer of the cuffs is not snug to your wrist, you will feel an eventual wind gust there
• Regular washing is required to keep the performance of the Gore-Tex membrane alive
