Iron Heart Ultra Heavy Flannel Workshirt (Blue X Black) should be some best heavy flannel shirts we have ever seen in this market!

The selvage ultra heavy flannel is slowly weaved from very old fashion machine and colors are over-dyed which will age gradually with wears and washes. The ultra heavy flannel is thick enough to call it as a JACKET rather than a shirt especially the brushed interior which is as comfy as cashmere which will always keep you warm even "The Winter Is Coming"
