The Maison

Phi 1.618 is a luxury leather goods Maison inspired by the golden ratio, eco-responsible and made in France

The golden ratio

The Maison Phi 1.618 was born in reference to the golden ratio, Phi.

Known since antiquity as the most elegant measurement of nature, this “divine proportion”, as it was called in the Middle Ages, governs the most beautiful works of nature and man: nautilus shells, cathedrals, the works of Leonardo da Vinci and even human DNA.

Our creations respect this proportion, which lends them elegance and timelessness.

When you wear a Phi 1.618 creation, it is not a belt or a bag that you are wearing, but the expression of the golden ratio.

The eco-responsibility

We select full grain leather hides of exceptional quality from the unused stocks of major French luxury houses and their associated tanners… Hides that, until recently, were destroyed.

By “upcycling” them, we reduce the environmental impact of fashion while ensuring the highest level of quality and durability.

And since our models are all made in France, their carbon footprint is very low, so they don’t have to travel around the world before arriving in your hands.

French Craftsmanship

Our models are created and manufactured in France according to the saddlery tradition to ensure exceptional quality and to preserve our savoir-faire. Each edge is threaded, dyed, heated, smoothed and sanded several times to ensure an ideal finish.

We create several colors of each model but in very limited editions. Sometimes only one of each color is produced. This allows each client to express their individuality while preserving our planet.

Our values

  • In the purity; the simpler a product is, the more perfection it requires
  • In French know-how

Consideration :

  • For our craftsmen and their traditional know-how

  • For the planet, by sourcing our leathers from the unused stocks of the major French luxury brands


The creative director

“After previously working in various professions such as international law and media, I decided that I wanted to follow my long term passion of creating with my hands and officially acquire my certification as an artisan in leather working. This certification was essential for me to create my Maison, Phi 1.618.

Passionate about creation in all its forms, the discovery of the golden ration acted like a revelation. It was obvious: this perfect proportion, present in nature since the beginning of time, resonated with my desire to propose creations that will last through time.

This perfection of Phi and the exigence and durability of my creations met the needs and desires of my friends and then, of course, my customers. ”
