Harold's Submarine Rucksack is made from high-quality, vegetable-tanned leather with a distinctive look and a special feel. The vintage surface of the bag is created through a washing process after production. Due to the open-pore surface, there may be color variations or slight irregularities. This is not a defect but a natural characteristic of the material that makes each bag unique. With its thoughtful and intelligently designed interior layout, this backpack is a practical and reliable companion for many occasions.
