The all-weather Cover Cloth Mile Marker has been updated with a more generous fit for increased layering room and ease of motion. The oil finish Cover Cloth exterior is Filson's lightest waxed canvas, giving the jacket rain- and wind-repellent utility while remaining light enough to wear in mild weather. Compatibility with Filson button-on hood and zip-in liners allows you to add insulation during winter months, making the Mile Marker one of Filson most versatile outerwear offerings.
