For the Studbag Backpack we use cowhide from Colombia. It is 100% vegetable tanned, light and has a silky shiny surface that remains lively due to its fine grain. The body of the bag is stabilized by riveted saddle leather straps. In this form, they ensure good usability of the bags and at the same time create the characteristic look of Studbags. With its padded compartment, the backpack offers protected space for notebooks of size 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 view.
