When we added flannel shirts to the shirt collection a few years ago, we had no idea they would become as popular as they have. It really shouldn't be a surprise. Every shirt is the real thing: yarn dyed, woven flannels, in a warm medium weight fabric, western pockets and flaps, and matching tinted snaps. Best of all, they are made in the USA and cost the same or less than many others that are imported. They are a perfect layer and look great under a vest, or over a t shirt! 100% Cotton, Made in USA.
