Westin W4 Winter Suit Extreme M Steel Grey

Westin W4 Winter Suit Extreme — Full-Day Warmth in the Harshest Conditions

The W4 Winter Suit Extreme is a two-piece thermal fishing suit built for anglers who refuse to be driven off the water by sub-zero temperatures and biting winter winds. Both jacket and pants combine waterproof, windproof, and breathable construction with serious insulation for all-day comfort.

Built to Block the Cold

The jacket features 200 g/m² body insulation and 160 g/m² in the sleeves, while the pants are insulated throughout at 160 g/m². The outer shell is 228T Nylon Taslon with PU coating, rated to 10,000 mm waterproof — enough to handle heavy rain and sleet. An extra-high fleece-lined collar and neoprene sleeve cuffs seal out wind at every opening, and the adjustable waist drawcord keeps cold air from creeping in.

Designed for Active Winter Fishing

The jacket includes six pockets and fleece-insulated hand warmer pockets, plus loops for an inflatable safety vest — a practical detail for boat and bank fishing alike. The fold-in hood is high-visibility red with a 180° view window, so you stay visible and aware in low-light conditions. Reinforced elbows and sleeves on the jacket, and reinforced knees and seat panel on the pants, ensure durability through a full season of hard use. YKK® front zippers on both pieces and wide leg zip closures make dressing easy even with cold hands.
