XLT - Men's tall 3.1 oz essential poplin shirt with full back yoke and back box pleat, left-chest pocket. Button-down collar, two-button adjustable cuffs and extra stiching at seams and buttons. An outstanding value in cool, comfortable poplin! This sharp wrinkle resistant polyester/cotton shirt is a bit thicker and more durable than most poplins for serious wearability. Plus smoother flat-felled side-seams, reinforces stitching all around and dyed-to-match buttons for that finishing touch.
