Not all flannels pass our litmus test, but it’s safe to say the 686 Sierra Fleece Flannel Shirt for men has earned its place as one of our favorites. The substantial fleece flannel fabric is ideal for chilly fall weather and midwinter wear, and the classic fit is roomy through the body without being too baggy through the torso or sleeves. All of this, of course, gives it a comfortable and stylish look that pairs well with everything from canvas work pants to denim jeans.
