This is a Porter outdoor-style backpack, built quite sturdily. I believe the capacity is around 25 liters. The concept of the series was to enjoy "aging and the wear and tear of denim." The retail price was over 50,000 yen, and in the seventh picture, it's almost the same model as the current HEAT Type-C. It was listed on the official Yoshida Kaban website until recently, but it's no longer available since it's from a previous series. It's made incredibly tough, so there are no tears, stains, or damage. Please understand that this is not the HEAT Type-C. Pattern/Design: Solid Color: Gray Material: Denim
