Thank you for viewing. This is a backpack my father used for mountain climbing in the past. I looked up the manufacturer from the logo on the bag, and it's very similar to a famous manufacturer, but the spelling is slightly different, so the manufacturer is unknown. Size: Approximately 45 x 35 x 23 cm The material appears to be thick, sturdy nylon fabric. Shipping will be done by folding the backpack. This is a used item that has been stored at home and has aged over time, so we are looking forward to purchases from those who understand this.
