The Flow Factor Down Jacket puts 650-fill RDS certified down inside a 2-layer ripstop shell built to move the way skiing actually moves. The down holds serious warmth through cold lift rides without adding stiffness or bulk at the shoulders, and a helmet-compatible hood with a three-way drawcord keeps coverage locked in on windy days. Underarm vents with mesh backing dump heat fast once the pace picks up, and an integrated RECCO reflector adds a layer of built-in safety for backcountry-adjacent days at the resort. What Our Gearhead(R) Experts Are Saying:"I've worn this on some of the coldest lift rides of the season and never felt like I was carrying extra weight for it. The down moves with my arms instead of fighting me on the way up, and once I'm working hard on a bootpack, the underarm vents let heat out fast enough that I never overheat."
