Shimano 2026–27 Winter Fishing Wear: New Gore-Tex Insulation 05 Is 10% Lighter and 2–3°C Warmer

November mornings on the surf are getting cold, so it is time to look at winter clothing. Shimano has released its 2026 autumn/winter (26AW) line-up, and the headline item is the new Gore-Tex Insulation Jacket 05, built with Gore-Tex’s new-generation ePE membrane. Below I compare the four jackets and pants that matter most for surf and pier anglers, with prices, weights and what changed.

Shimano 2026 winter wear: four key items compared

Prices are Shimano’s suggested retail prices before tax; weights are reference figures for size L. The ES Insulation Jacket 03 price varies by colour.

Gore-Tex Insulation Jacket 05 [RB-032Y]

What changed from the previous model

• New-generation Gore-Tex ePE membrane: about 10% lighter than before (size L)
• More insulation: 100–120 g/m² raised to 120–140 g/m² (140 g on body, 120 g on arms and underarms)
• Heat-retaining carbon-thread lining: inside temperature 2–3°C higher than the previous model
• Anti-static tape: reduces the static shock when you take it on and off

The point here is that it got lighter, gained more insulation and runs 2–3°C warmer at the same time. Winter jackets usually trade weight for warmth; this update improves both.

Aerocapsule is a hollow polyester fibre that traps air. Compared with down it is said to keep its loft when wet and dry faster, which is a real advantage when you are getting spray and rain on the coast.

Angler-specific details

The underarms have less padding so heat does not build up when you walk. Cuffs are double: the outer cuff has no tab so line does not snag, while the inner cuff seals the wrist. The cut lets you bend your elbows when lifting the rod without the jacket riding up, and the pockets stay reachable even with a shoulder- or waist-type life jacket on.

Gore-Tex Insulation Pants 05 [RB-033Y]

Same story as the jacket: about 10% lighter with the new Gore-Tex and 2–3°C warmer inside. The insulation is mapped, thicker on the thighs and thinner below the knee and around the crotch, so you stay warm without losing mobility. A stretch brushed panel at the waist stops wind getting in at your back when you crouch or sit, which helps on the pier and on boats. Gusseted hem zips fit over shoes or short boots.

ES Insulation Jacket 03 [RB-034Z]

Part of the Exsence (ES) series, this is a feature-packed winter jacket for seabass and lure anglers. Its big selling point is 13 pockets, plus D-rings, a simple rod holder and a detachable lens cloth on the left chest. Seawater-resistant water repellency, a storm flap with snap buttons over the zip and drawcords on the hood and hem are all aimed at standing for hours in harbours and on the surf on winter nights. At 1,055 g it is heavy, so I think it suits fishing one spot patiently more than walking long beaches.

Active Insulation Jacket [WJ-055Z]

By far the lightest of the four. It is water-repellent rather than waterproof, so the best use is as a mid-layer under your rain jacket. Walking the surf makes you sweat, so the uninsulated underarms make sense. The pockets are lined with brushed fabric and work as hand warmers.

How to choose for surf and pier fishing

Surf fishing is a cycle of walking, sweating, stopping and getting cold. A thin padded layer under a waterproof shell is often easier to manage than one very warm outer jacket. If you sit and wait on a pier, a thick top-and-bottom set is more comfortable.

Think in layers

• Base: a synthetic inner that moves sweat away quickly; avoid cotton
• Mid: fleece or a thin padded jacket to create an air layer
• Outer: a breathable waterproof shell to stop wind and water
• Extremities: gloves, neck warmer and socks to protect neck, wrists and ankles

The 26AW range also includes dry innerwear (with an extra-thick double layer model), dry sweatshirts, a double-thick neck warmer and several winter gloves. If you are replacing your jacket, it is worth updating the base layers and accessories as well.

My take: light and warm is this year’s theme

Across the whole line-up, the keywords are weight reduction and insulation that copes with getting wet. The Gore-Tex Insulation 05 in particular is 10% lighter, has more fill and runs 2–3°C warmer, tackling the usual problem of bulky winter clothing that restricts casting. On the surf or the pier, once the cold breaks your concentration the session is over, so clothing is a good investment if you fish through winter.

Summary

• Gore-Tex Insulation Jacket 05 (¥44,000) and Pants 05 (¥34,000) are about 10% lighter thanks to the new Gore-Tex
• Insulation raised to 120–140 g/m², and the lining raises inside temperature by 2–3°C
• ES Insulation Jacket 03 is the multi-function model with 13 pockets (¥47,000–49,000)
• Active Insulation Jacket is a light 280 g padded layer (¥23,000)
