The Filson Men's Seattle Moleskin Long-Sleeve Shirt uses warm, durable, super-soft moleskin to keep you comfortable while you work, tinker away on your old truck, or help with the yard work. Its Moleskin cotton fabric features a twilled weave that forms a thick, dense cloth for stellar wind resistance. Filson gave this button-up relaxed shoulders and a Seattle fit which means it has a tailored cut that allows room for mobility through the shoulders while also making the shirt sit comfortably closer to your body. A center back pleat, adjustable cuffs, straight collar, and two expandable chest pockets with button flap closure round out this shirt's fine features.
