Long-sleeved checkered shirt with buttons and a pocket. - Color: Checkered pattern (navy, red, white, yellow) - Design: Long-sleeved shirt, button-down, with a pocket - Material: 100% cotton Can be worn except in the peak of summer. In winter, wear a turtleneck underneath. Especially during the changing seasons, I wore it over a short-sleeved T-shirt. I've also worn it for camping, etc. The fabric is a stiff material. Thank you for looking.
