On the days Mother Nature left a foot of fresh snow on your doorstep overnight and is still howling angrily by morning, pull on the Men's Fjallraven Singi Heavy Flannel Shirt to defend against the deep chill in the air, then get to work. Whether you're filling the woodstove, thawing out the pipes, or shoveling driveways for all the neighbors, the Singi's soft, sturdy cotton fabric will keep you warm until the very last chore is done.
