From the manufacturer Arakawa, this is a Paul & Joe sweatsuit. I think it would be great as relaxing wear or pajamas, and also for training camps or travel. Size: L It's warm with a fleece lining. Please be sure to check my profile. This is a home-stored item and is being sold by an amateur, so it is not perfect. Please refrain from purchasing if you are concerned. I may have overlooked some loose threads or stains, but please understand this before purchasing. #Sweatshirt #FleeceLined #Pajamas #Sleepwear #Men'sPajamas #Gentlemen'sSleepwear #Roomwear #RelaxingWear #RelaxingWear #TrainingCamp #Travel #Present Color...Gray系 (Gray-ish)
