The Fortis Marine Olive Trousers have been meticulously designed and developed for the dedicated angler right down to their articulated knees, knee-length boot zips and press stud ankle adjustments. These waterproof, breathable fishing trousers are the protective outer layer in Fortis' layering system. The Triflex fabric is highly breathable and wicks away moisture generated from high levels of activity. So it's easy to forget you're wearing them until the showers roll in.
