For the Studbag Backpack we use cowhide from Colombia. It is 100% vegetable tanned, light and has a silky shiny surface, which stays alive due to its fine grain. The body of the bag is stabilized by riveted saddle leather straps. In this form they ensure that the bags are easy to use and at the same time create the characteristic look of the studbags. With its padded compartment, the backpack offers protected space for notebooks measuring 26 x 31 cm. Over time, the leather develops a fine patina that protects it from dirt and moisture. The insensitive, light mottled lining provides a pleasant interior.
