The Extra Heavy Flannel definitely lives up to its name, coming in at a beefy 15.5oz, an ounce heavier than their normal heavy flannels. Woven on power looms, creating intricate color combinations, the fabric has a bit of texture and is slightly brushed for a comfortable feel. While these shirts are substantial, they contort to the body comfortably. The dye on the fabric will fade with time and wear, leading to that sought-after vintage flannel look.
