Bag Size M

Classic messenger bag.

The classic messenger bag from which it had all started. Hundreds of hours on the bike and continuous cooperation with couriers resulted in many improvements made to the original design. We believe that its current form will satisfy even the most demanding customers. Practical details ensure comfort and the unique inner layer of PVC ensures a solid protection against heavy rains and water in general.
Made of Cordura®.

Made by hands in EU, in our workshop in Warsaw.
