great flannel
Color: Orange, Size: XX-Large
finally, a flannel shirt that is not made like all other cookie-cutter flannels. this one a bit different. body is a bit shorter (1-1.5”). and sleeves, a touch longer, for each size.
plus, it’s perfect thickness for early mornings in summer, or even mid-day in fall.
awesome flannel shirt…. just heads up… order one size bigger than normal, and you’ll love this flannel. (especially for us men & women who have a slightly longer arms than most)
