- The Carrik has a roll-top system expanding its capacity from 17 to 22 liters. The extra load can be easily lifted thanks to the padded back panel. The Carrik has additional front pockets that maximize not only the design but also the function of the backpack. A jacket can be clamped under the front pocket with a YKK zipper when needed. The aluminum closures give the Carrik a superb look.
