This is a backpack from THE NORTH FACE. I've been using it for about a year, so it shows some signs of wear, but there's no damage to the exterior, so I think it can still be used. I don't know the size, so please look it up using the product number. Thank you. - Brand: THE NORTH FACE - Color: Black/Yellow - Product Number: NMJ81900 - Style: Backpack - Features: Water-resistant material
