This lightweight hiking jacket from Columbia oozes versatility. The stretchy 2-way fabric and 60g stretch thermal insulation provide the flex you need on the most challenging of trails — and beyond. Wear the jacket by itself or layer it with a rain shell, thanks to the 3-in-1 Interchange system, for extra protection from the cold during the chilliest months. For an even more bespoke fit, use the drawcord hem to stop those freezing mountain winds from entering. On and off the trails, this jacket is indispensable.
