A lightweight take on the Iconic Alaskan Guide Shirt from Filson, constructed from a 5oz prewashed, breathable cotton twill that is both soft ad durable. Pleated rear shoulders provides a full range of movement and expandable, gusseted chest pockets with button-close flaps keep small valuables handy and secure. Finished with custom Filson-logo buttons on the front closure and adjustable cuffs that are built with tough, chip resistant polyester for years of durability.
