A comfortable organic cotton shell in yarn-dyed flannel lined with a 100% recycled polyester twill and insulated with 60-g Thermogreen® 100% recycled polyester the Patagonia Insulated Organic Cotton Midweight Fjord Men's Flannel Shirt is your go-to autumn layering piece for getting outside in cooler weather. Just enough insulation to make this a light warm jacket, not too much to keep it cozy indoors, and layer it up under a vest or shell and you get even more range from this workwear inspired piece with its buttoning front placket and nice handwarmer pockets for cool days. A straight cut hem, workwear inspired, and everyday comfortable, this will take the edge off of a chilly autumn day, is the perfect accompaniment to a campfire, and is the shirt to shrug into at after a day in the backcountry when you need to shake off the day’s cold.
