Green x Navy/White Check Pattern - This is a seersucker-style pajama set. I think you'll be able to wear it comfortably even when spending time in a room with air conditioning, wearing long sleeves and long pants. I've only worn it once or twice. There is a faint name written on the collar. I think it will come off with washing. - Color: Green x Navy/White - Design: Check Pattern - Type: Pajama Set - Size: M - Men's Please refrain from purchasing if you are sensitive to used items. *I will wash it before listing it for sale.*
