Filson’s Washed Feather Cloth Shirt is an extra-soft version of the classic, all-natural shirt that’s been a warm-weather staple for decades. When the day heats up, there’s nothing more comfortable against your skin than lightweight 100% cotton, and with this heavily-prewashed variant, you can enjoy that exceptional comfort from the first day. Center-back box pleat for ease of motion. Button-flap expandable chest pockets.
