Westin W4 Trousers 15000mm 5000g/m²/24h Gunmetal 3XL

Westin W4 Trousers — All-Weather Fishing Protection in Size XXXL

Built for anglers who refuse to let the weather decide their session, the Westin W4 Trousers combine serious waterproofing with genuine breathability in a tough, feature-packed package sized for larger builds.

Weatherproof Construction That Works

A 2-layer Taslan Oxford and Rip-Stop nylon shell delivers a 15,000 mm waterproof rating while remaining breathable at 5,000 g/m²/24h — enough to handle rain-lashed bank sessions and boat fishing without overheating. All seams are fully taped and the Eco DWR Bionic finish sheds water droplets rapidly, keeping you dry from the outside in.

Built to Last Through Hard Use

Exposed high-wear areas are reinforced with 100% heavy nylon, extending the life of the trousers through repeated contact with bank edges, boat gunwales, and rough ground. Ankle-to-knee side zippers make pulling the trousers over boots straightforward, and the hook-and-loop hem adjustment seals out draughts around the foot. Removable elasticated braces keep everything in place during active fishing. Two zipped security pockets hold keys and essentials, and two large thigh pockets put rigs, forceps, and bite alarms within immediate reach.

Choose the Right Size

The W4 Trousers are available in the same Gunmetal colourway across six sizes, all sharing the same 15,000 mm / 5,000 g/m²/24h specification. Select the size that gives you full freedom of movement over base layers:

• S — trim fit, lighter build, minimal base layering

• M — standard fit, single mid-layer clearance

• L — relaxed fit over a fleece mid-layer

• XL — comfortable fit with room for heavier winter underlayers

• XXL — generous cut for broader frames or multiple base layers

• XXXL — maximum cut for larger builds or full winter underlayer systems
