The iconic Filson Alaskan Guide shirt is, well, iconic for a reason. It's made from soft but durable, breathable, and wind-resistant cotton flannel, and it has a pleated back so you get extra mobility to chop wood, work on your fly cast, or tear it up at karaoke night. Plus, added details like two flap pockets and adjustable button cuffs ensure that this will probably be the best shirt you've ever owned.
