If you're willing to pay a premium to keep warm this winter, you need look no further than Canada Goose's Snow Mantra Parka, billed as "the warmest coat on earth." How does the alpine brand back up the lofty claim? It field tests its garments at the coldest places on earth, and the Snow Mantra's 675 fill power white goose down is able to withstand temps rated at minus 25 degrees Fahrenheit and below. Details include a removable coyote fur ruff surrounding a 3-way adjustable tunnel hood, high-pile fleece lined windguard from top to bottom, fleece-lined handwarmer pockets and an extra layer of down-proof nylon lining. Retailing for $1,275 and available in three colors, the Snow Mantra Parka can be purchased directly from Canada Goose.
