When maximum warmth, packability and stretch can&&';;t be compromised, reach for the Sitkin. The full-zip hooded down jacket is made with 800-fill Allied Feather down insulation to keep things toasty, while the 87% nylon 13% elastane fabric is super stretchy for premium mobility. Stash the Sitkin into its own pocket and toss it in a pack when you head into the mountains, then put in on under a shell and cinch things down when conditions turn nasty. Zip handwarmer and chest pockets keep your digits warm and essentials organized. The Sitkin also pairs well with a cold beverage and warm fire at the end of a day in the mountains.
