Ever been walking downtown and swear you saw a polar bear one street over? The North Face Men's Sabretooth Parka is designed for those Icelandic days. This 550-fill down jacket is protected by a 2-layer Gore-Tex waterproof/breathable shell for protection against the nastiest rain and snow. An insulated hood has a detachable fur rim so you can go for either the "warm as an Eskimo" or something more suited to hanging out downtown.
Bottom Line: It won't save you from the polar bears, but you'll be as warm as one.
