This is a backpack/daypack/rucksack from the PORTER "TANKER" series, which is synonymous with the brand. Color: Black Material: Nylon twill (polyester cotton bonding) I purchased this several years ago and used it a few dozen times a year, not for daily use. There are signs of use, such as scratches on the metal parts. There is a slight stain on the back of the top of the rucksack, as shown in photo 5. There are several scratches on the inside bottom, but there are no problems with use. Please check the photos. This is a used item, so please refrain from purchasing if you are concerned about minor imperfections. I will upload photos of any areas of concern. Thank you. I have set the price based on the market value.
