The brand Freitag is one that should inspire people to think outside of the box. This brand does all kind of bags specially the messenger one. They are made with materials like well-traveled truck tarpaulins, unraveled seat belts, bicycle inner tubes beyond repair and recycled airbags. Since they are made or trunk tarpaulins they are pretty resistant!
You could go until the 4th box.
Each bag they produce is unique, since it will be cut out of a unique truck tarpaulins. This image simple translate this point very well,

The other weekend while strolling in Cologne we ended up finding a Freitag shop, i really like their minimalist and well organized way of showing their products.
They had quite a lot of unique products!
Also if by any change you have some spare truck tarpaulins you can always sell them to Freitag :)
Simple, recycled and unique!
