Portuguese Flannel has built a reputation on taking timeless patterns and weaving them into shirts you’ll wear for years. The Alpi Long Sleeve carries that tradition forward with a classic red-and-green plaid cut from soft 100% cotton. Finished with mother-of-pearl buttons and crafted in Portugal at the family-run mills they’ve operated since 1935, it’s an everyday essential with just the right mix of rugged and refined. Wear it buttoned up with chinos, layer it open over a tee, or pack it up for your next weekend in the mountains—this one’s built for it all.
