Thank you for viewing from among many items. This is a large-capacity backpack from Coleman. Camping, large backpack, ski trip, travel, school trip It's lightweight and has a large capacity. When you open the side zipper, it becomes even larger, which is convenient when you have more luggage, such as wet items, laundry, or souvenirs. Expanding the gusset transforms it into a maximum capacity of 50 liters! Side pockets can easily store water bottles, 500ml PET bottles, rain gear, etc. Size [Body size] Approximately 53-67 x 45 x 18cm [Weight] 830g [Capacity] 42L - 50L Black I think this color is hard to find. I used it once for camping. There may be some stains, but it looks clean.
