Kalm Backpack - Raw Umber

  • SFr. 149.00
Tax included. Shipping calculated at checkout.

The Kalm is similar to the Blok Medium but its design is cleaner. If you are looking for a simple backpack with only the basic functions, then the Kalm is made for you. But do not worry: Your 15" laptop is still protected by a padded compartment and can be reached quickly through a side-zipper access.
