This classic men's long-sleeve flannel shirt features a rugged navy-based plaid pattern with crisp white, gray, and subtle rust-orange stripes, crafted using premium 100% cotton with a distinctive brushed 'máo máo' (napped/mill-finish) texture for enhanced softness and warmth. The shirt includes a standard pointed collar, button-down front with matching dark metal buttons, and a single chest pocket with buttoned flap—designed for durability and timeless utility. Its relaxed yet tailored fit makes it ideal for layering in cooler seasons or wearing solo in mild weather. The fabric’s磨毛工艺 (brushed finish) provides superior comfort against the skin while maintaining structure, perfect for daily wear, outdoor activities, or smart-casual settings. Ideal for autumn and winter, this versatile piece bridges workwear heritage with modern casual styling—pair with jeans, chinos, or under a jacket for elevated layering.
