A Dedicated Waterproof OverTrouser For Wet Weather Conditions
The ultimate waterproof outer shell. Built for the outdoors, the Fortis Marine Overtrouser provides essential protection as you battle the elements.
Meticulously designed and developed for the dedicated angler, this fully waterproof, highly breathable and ergonomically engineered overtrouser is the protective outer layer for our technical layering system and the perfect accompaniment to our Marine Jacket. Particular attention has been made to the cut of the trouser with its articulated knees – an ergonomic feature providing unrivalled movement and mobility. Our Triflex fabric boasts additional stretch, and combined with technical tailoring around the crotch, this ensures you’re not restricted by any seams when you crouch down.
A classic and relaxed fit means you can layer up accordingly throughout the seasons without restriction.
The knee-length zips with press stud ankle adjustments are comfortable with all footwear, no matter what the season. A rear zippered pocket keeps any valuables safe.
Our Triflex fabric is highly breathable and wicks away moisture generated from high levels of activity. So if you’re walking miles in search of the fish in inclement conditions, it’s easy to forget you’re wearing a waterproof until the showers roll in.
The Marine Overtrouser provides ultimate waterproof weather protection.

Marine Waterproof Trousers – Fully Waterproof, Highly Breathable Outer Shell
The Marine Waterproof Trousers form the protective outer layer of our technical system. Built from our premium 3-layer Triflex™ fabric, they deliver complete weather defence while remaining exceptionally breathable and flexible. Purpose-built for anglers who refuse to let the rain dictate the session.
Engineered for Movement & All-Season Layering
A classic, comfortable fit allows room for seasonal layering without restricting mobility. Darted knees, a diamond gusset and ergonomic patterning ensure natural movement whether crouching, climbing or covering ground. Press-stud ankle adjustments accommodate all footwear setups.
Waterproof Performance When It Matters
Fully taped seams, a 25,000mm waterproof rating and superb breathability keep you dry from both the outside and the inside. Triflex™ fabric stretches with the body and wicks moisture efficiently, making these the go-to over-trousers for long walks, stormy weather and high-output sessions.
Practical Access & Lightweight Construction
YKK® AquaGuard® Vislon® zips provide secure, easy access to valuables, while knee-length side zips with storm flaps let you get in and out quickly — even with boots on. At just 430g (M), they remain incredibly lightweight without sacrificing long-term durability.
