Nearly nine decades of flannel mastery goes into the L.L. Bean Scotch Plaid Flannel Shirt. The exclusive Portuguese cotton gives you the royal treatment—longer fibers woven together, then brushed eight times per side until a master weaver gives the approval. The result? Flannel that's genuinely tougher and more luxurious than the rest. These authentic Tartans are yarn-dyed to match historical Scottish registry standard, ensuring your plaid stays vibrant wash after wash. Machine washable and built to become a trusted favorite for generations to come.
