Filson's iconic styles receive a toughness upgrade with the Alcan jacket. The tough, weather-resistant layer features a heavy-duty waxed-canvas shell that benefits from a special paraffin wax provided by British Millerain for water resistance that's been tested for over a century. And for extra protection, the jacket also has a reinforced layer of Cordura ballistic nylon that covers the shoulders and upper arms. And it's just as versatile beneath the surface thanks to 60-gram PrimaLoft Gold quilting: the warmest and lightest synthetic insulation available. Perfect for riders or anyone that's ready to take on the elements, each jacket is finished with rib-knit cuffs and a collar with a custom fit to seal out the wind, an interior zipped pocket, and zippered front-hand pockets lined with Moleskin.
