Shrug off cold and biting temps with the Patagonia Men's Hi-Loft Down Jacket. Thermal efficiency is the name of the game when you're hunkered down at altitude, and with a generous dose of high loft 600-fill goose down, this jacket insulates your core so you stay nice and toasty when winter weather would have it otherwise. Recycled ripstop fabric puts up with a bit of abuse, and a DWR coating sheds moisture. Since the jacket is insulated with traceable down, you can rest assured that no geese were force-fed or live-plucked to make this jacket.
