waste of money. not a flannel
Color: Purple, Size: X-Large
sizing is way off. the material isn't that of even a Walmart flannel shirt. it's a stiff crappy material. I leaned down to pick something up and I tore the shoulders of the shirt. horrible stitching.

Good quality true to size
Color: Orange, Size: Medium
Good material. My brother is 6’1 and 165 pounds and was able to fit the medium perfectly. So glad I didn’t get a large even though a large woulda been cool just a little oversized probably
