Efficiency in the alpine means high steps, simulclimbing and fast belay transitions. And, of course, top-notch insulation. Our new Fitz Roy Down Jacket uses ethically sourced and traceable 800-fill-power down in a high-loft quilting design- larger, loftier chambers keeps your warmth in the 100% nylon shell with snow-shedding DWR (strong water repellent) finish, which uses a special high-sheen fabric construction atop the shoulders for enhanced moisture resistance. Underarm gussets improve range of ful motion and the center-front zipper has an internal storm flap and a soft, kissing-welt zipper garage with a micro-fleece-lined chin-flap for bare skin comfort. A drawcorded hem seals-in heat and cinches from inside the two zippered handwarmer pockets (another zippered pocket sits on the outer left chest). Soft, low profile, internal elastic-bound cuffs push-up easily, and the included stuff sack has a built-in clip-in loop.
