Ultra-heavyweight (UHF) flannel shirt that's heavy, tough, but amazingly wearable. The 12 ounce fabric is woven with Aspero cotton from the foothills of the Andes. It is double brushed on the inside and single on the outside, resulting in a very soft yet strong, thick, warm and windproof flannel. This shirt is a wardrobe staple - a work shirt in red/black buffalo check.
