Philipp Bree insists on the use of high quality materials sourced from selected, long-established European manufacturers. Production of the bags is entrusted to the expert craftworkers at three family businesses of bag-makers in Europe. All of the three firms have been plying their trade for generations.


We source the leathers from a Belgian tannery that specialised in the vegetable tanning of cowhide as early as 1873. This preserves the natural structure, supple feel and spicy scent of the leather. Only about ten percent of all leathers worldwide are vegetable-tanned. Natural leather is therefore considered a precious rarity. 

The linings are made of calf suede, which we source from a Polish manufacturer that has been producing split leather for over 150 years. All leathers used in the collection are certified with the highest awards.


The linen is extremely hard-wearing and is woven by an Italian family business that was already known in the 19th century for its robust ropes, which still hold numerous church bells in Tuscany today. 

Linen is one of the oldest natural textile fabrics, but is used today for less than one percent of all textile fibres. The reason is the demanding conditions for cultivation. After all, the plant only flowers for a single day, then it is harvested. And little has changed in the manual labour-intensive processing for thousands of years.


The fittings are designed for us and made of solid brass in an Italian workshop. The family business is in its second generation, and the founder still welds here herself. 

 Their surfaces are refined over time by the development of a very specific patina.

All zips are also made of solid brass. The teeth are set very tightly, polished several times, and open and close very easily. They are extremely smooth and therefore gentle on hands and scratch-sensitive surfaces. They are produced in the middle of Germany.


LEFA is made from recycled leather obtained from surplus leather processing. It is first granulated and then pressed with natural rubber from trees. This creates a recycled leather quality that is 80% leather and 20% natural rubber. In a final step, the leather is coated in a patented process. The result is an extremely durable, water-repellent and easy-care material that can be returned to the cycle at the end of its life cycle.


The selected yarn has excellent tear and abrasion resistance. It has been spun by a specialised family business in Breisgau for over 150 years.
