U21 stands for Urban 21L – it has 21 liters of storage space in the main compartment. It was designed by our good friend from Singapore. He wanted to keep the design simple yet spacious. Besides the 21 liter main storage, it features a 2 front pouches and an expandable side pocket which can easily accommodate a 1L bottle. For the bottom, premium industrial leather is used for toughness and durability.
