This is an innerwear garment from Otafuku Gloves, men's size M, product number JW-620. It's contact-cooling and quick-drying, so I used it as an inner layer for hiking and cycling during the hot season. How about it for the upcoming hot season? There are no noticeable scratches or stains, but please understand that this is a used item before considering a purchase. Please be sure to read my profile (^^)
