The Submarine Backpack rollover S is made of washed cowhide with a slightly shiny surface and a rich feel. The spacious zippered main compartment is flexible in height thanks to the rolled-up closure. It offers a padded laptop compartment, making it the ideal mobile companion for work or and leisure. The side zippered compartments (front and back) are very practical especially when worn as a backpack on the go. However, the bag can also be used as a messenger bag. For this purpose, the "backpack carrying strap" is converted by simple handles to the courier bag carrying strap.
