Not only is it our favorite jacket this year, but has been our favorite for the past five years, through four review processes, and literally countless days out in the backcountry. The newest version of the Arc'teryx Alpha FL is virtually unchanged from last year, when it was upgraded from GORE-TEX Active to the more durable GORE-TEX Pro three-layer membrane. This jacket excels at everything from day hikes to multi-month expeditions - it's a backcountry enthusiast's dream come true.
Arc'teryx has updated the colors of this jacket for the winter of 2016. The Alpha FL is now available in four colors: Lithium, Adriatic Blue, Blaze, and Bamboo. The rest of the jacket remains unchanged.
