Montane Duality Jacket is a versatile shell jacket with integrated insulation, developed for hiking and trekking in demanding winter conditions. It combines PFAS-free GORE-TEX ePE 2-layer nylon fabric with lightweight, recycled synthetic insulation that is body-mapped to keep the core warm without restricting movement.

With built-in breathability (RET <13) and an adjustable hood with collar, the jacket offers reliable protection against wind and precipitation. An extended fit and weather-protected hand pockets provide extra comfort and coverage, while an adjustable hem and an internal chest pocket add practical functionality.
