Hajo Medium Backpack


This minimalist backpack is suitable for any occasion. Whether on the road by bike, shopping or in the nightlife. The roll-top closes with a hook and loop fastener and allows a practical filling of the Hajo backpack. 

Microscopic glass beads are covered on a 3D diamond structure to reject light at night in multiple directions and so boost your visibility in traffic. During daytime, the combination of four different fabric surfaces provide interesting details even so all of them are almost black. 

The Satellite Series is only available in our online store as a brand exclusive item
