Unused item. Men's M size There is no tag, so the material is unknown. I think it's likely cotton. I was wearing a different color, and it was a cool and refreshing fabric. Short sleeves and long pants. The pants have pockets. There are fold wrinkles. I have stored it for a long time after purchasing it, so there may be a musty smell from the closet. Please note that this is a personal inspection, and there may be oversights. If you are concerned, please refrain from purchasing. I plan to ship via Yu-packet Post or Nekopos. Please check my profile before purchasing (^ ^)
