THE FIVE PILLARS - NO COMPROMISE
Every decision in the development of this leather traces back to five things we needed it to do. Not five features. Five requirements — non-negotiable, and in tension with each other in ways that made the whole thing genuinely difficult. But if we were going to do it, we were going to do it right.
-
THE EYE AND FEEL TEST. It has to look like leather and feel like leather — immediately, without question. Not an approximation. Not something that reads as leather from a distance and reveals itself as something else in the hand. Authentic, all the way through. The eye and the hand should both confirm it at first contact.
-
NO PLASTICKY SURFACE COATING. It couldn’t look manufactured. Many established houses use thick surface polyurethane (PU) topcoats and acrylic topcoats coatings on oil wax leathers because it makes production easier and durability more predictable. We understood the logic. We rejected it.
Those coatings put a film between your hand and the material. What you are touching is no longer leather — it is PU or acrylic sitting on top of leather. The result is sealed, manufactured, plasticky. And over time, that coating cracks, matte-ifies, and peels. It cannot be repaired, because you cannot reach what is underneath. No film. Soft, responsive, alive. -
FINISH HOLDS UNDER REAL WORLD USE. The oil wax finish had to hold. Not just look like it would hold — actually hold, under the kind of use a bag sees when someone carries it every day. We thought we had solved this in August 2025, sourcing from a tannery that supplies a major global luxury brand. After eight weeks of heavy use, the finish began to rub off at contact points, the surface becoming increasingly matte, losing exactly the quality we had built it to carry. We hadn't solved it. We went back.
-
HUE, SHEEN, SUBTLE TWO TONE. The color needed a specific quality — a hue, a sheen, and a metamorphosis in the light that is reminiscent of nature’s skins. The skin of an olive. A grape at harvest. A blackberry at its deepest, just before it falls. A surface that reads differently as the light moves across it, not because anything has been done to it, but because of what it already is.
-
STRUCTURAL CHARACTER. How it behaves over time. Semi-structured — holding its form on its own, presenting with a specific rigidity on day one. Softening gradually with carry. Developing with use. But never, under any circumstances, collapsing. The structure is not a fixed state. It is a quality that evolves while remaining itself.
These five things are what we spent fifteen months trying to first find, then developing on our own.
WHAT WE FOUND
We started in October 2024. LWG Gold certification, the Leather Working Group’s highest standard for environmental and ethical practice, was the baseline from the beginning. Not a decision we arrived at. The starting filter. The ethics and the quality are, at that level, the same requirement. Tanneries that operate with that degree of rigor produce better leather, source better and provide better working conditions.
The oil wax leather market has two failure modes for our standards, and between them we found there was very little.
On one end: leathers that fail the eye and feel test immediately. Too coated. Too sealed. A PU or acrylic film sitting on the hide, uniform and manufactured. The durability is there. The leather is not.
On the other end: oil wax leathers that appear exceptional until you live with them. Right feel, right weight, right surface on day one. And then weeks of real carry and the problems emerge. Rippling, cracking, the finish lifting at contact points. Beautiful at first. Not built for what comes after. Only for use in delicate leather goods - not everyday use bags.
Then you have the traditional oil waxed (it’s own category) that purists say is the best. But way too stiff and rigid. Not pretty - doesn’t pass the luxurious eye test.
We were warned of this. Found out the hard way.
THE BENCHMARK
Over the course of the search, we contacted more than two dozen LWG Gold certified tanneries. Including some of the largest in the world — suppliers to houses like Thom Browne, Prada, Songmont, Balenciaga. We held their leathers. We tested them seriously. We needed to understand what the ceiling of what already existed actually looked like.
It wasn’t enough. Not because those leathers are poor - they are not. But the requirements of the KIMIAS object are specific to our own standards, and no existing product was designed to meet all five simultaneously. All of them had one compromise.
The large tanneries had one consistent problem: they were not willing to work on something custom. Their model is scale. They produce at volume for clients with volume. A new brand with unconventional, specific requirements was not a conversation they had any incentive to have.
The same resistance appeared when we approached Italian and European production houses about manufacturing the bag itself. Many told us our design couldn’t be achieved. The Contour silhouette, the semi-structured construction, the specific curvature architecture we needed — not possible, they said, or not worth attempting. One or two were willing, but would constantly put us to the back of the line. We need another 2-3 months to make another sample. So on and so forth.
I understand why. They were excellent at executing within what they already knew how to make. We were asking them to approach a problem differently, and that is a fundamentally different skill. It is the difference between an established auto manufacturer and a new car company. The established players have infrastructure, tradition, deep process knowledge — and within those constraints, they are exceptional. But if you are building something that doesn’t fit the existing template, that same infrastructure becomes a wall. We needed partners willing to think from first principles. Not from precedent.
THE SETBACK
That was even more vital because after starting our first prototypes across Europe and eventually Asia in late 2024, we thought we had finished in August 2025. The manufacturing decision to move from Europe to Asia is a different story for now.
But by August 2025, the prototype looked right. The feel was there. The color was beautiful. We had finalized the construction, interfacing and design. But we don’t go off hope - so we put it through wear and use testing - the kind of sustained, daily contact a bag actually sees over weeks of real carry. Within eight weeks, the problems appeared. Rippling. Cracking at stress points. The oil wax finish beginning to lift and rub off at contact points, the surface becoming increasingly matte, losing exactly the quality we had built it to hold. We had been warned by nearly everyone this might be an issue given we wanted all five qualities.
But we went back.
I want to be direct about what that moment was: not a crisis. A clarification. We had been working with a leather that was close enough to believe in and not close enough to build on. The failure told us precisely where the gap was and what we needed to solve. Sometimes that is the only way to learn the exact shape of a problem.
The instinct was simple: keep going. Keep banging your head on the door. Don’t settle for what almost works.
THE PARTNER
The tannery we committed to is medium-sized, LWG Gold certified, based in Dongguan. And boy were we thrilled.
Our main point of contact, the leather expert we developed this with over lots of tea, cigarettes and discussions, came to the problem with a background that extended well beyond the traditional leather industry. My primary point of contact came from a tech background for over a decade, developing and implementing new products and systems. That experience gave him a different kind of flexibility. I instinctively felt this was almost like me - someone with no experience in this industry, but deep expertise in problem solving across my days at the top international law firm and opening Michelin restaurants.
Most tanneries operate within inherited frameworks: this is how oil wax leather is made, these are the parameters, these are the outcomes available to you. But he could step outside of that. We could ideate together without being constrained by what had always been done. First principles. Not tradition.
I felt it from the first conversation. A sense of kinship - two people approaching the same problem from outside the standard path. Thinking about it from the ground up rather than from tradition downward. That matters in development work. Trust is not a soft consideration. It is a material requirement. Without it, the iterations we needed to run together would not have been possible.
THE ITERATIONS
What followed was a period of focused, specific development. Samples moving back and forth, each one targeting a defined variable. Many iterations. About two weeks of production and a week of shipping between each.
The thickness came first. We had originally been developing at a heavier weight, with the intention of skiving the leather down during construction. The process introduced inconsistencies we couldn’t resolve cleanly. We landed on a final weight of 1.2 to 1.4 millimeters — refined enough to carry the sculptural body language of the Contour silhouette, substantial enough to hold its architecture through real use.
The dye was the key decision. Full aniline dyeing — the dye penetrates the entire hide rather than coating the surface. This is the highest standard in leather dyeing. The color lives inside the material, not on top of it. The natural grain shows through exactly as it is. The hide breathes, moves, and changes with carry without the color fracturing at stress points. And critically: no artificial topcoat required to hold it. The dye penetration itself provides the stability — the durability we needed, without the film that would have destroyed everything else we were building for.
The two-tone required the most precision. Oil wax leathers typically need extended tumbling — many hours — to produce the subtle color metamorphosis where grain peaks and valleys catch the light differently. The conventional approach over-softens the leather, removing the structural character we needed to preserve. We found that full aniline dyeing, combined with a significantly shortened tumbling time, plus some other changes in the order of operations of the leather process, combined with the type of hide (some regions produce harder and softer hides, larger and smaller hides - every variable plays a factor after leather undergoes processing) produced the desired color metamorphosis that reflects skin, with greater control and the structure intact. The dye penetration does the work. The result: a surface variation that is precise, natural, and structurally sound.
WHERE WE LANDED - 15 MONTHS LATER
Grade A hides, hand-selected from Spain, the United States and the Shandong Province of China. Full grain. Full aniline dyed. Custom oil wax finish — infused into the hide, not applied to its surface. No polyurethane topcoat. No acrylic sealant. Developed in exclusive partnership with an LWG Gold certified tannery in Dongguan.
The wear and use test confirmed it. The same conditions that ended the August prototype — sustained daily carry, repeated contact, weeks of real use — held. The finish held. The color held. The structure did what we designed it to do: present with rigidity on day one, soften gradually with carry, develop into a beautiful, absolutely gorgeous skin without losing structural integrity or surface / feel integrity.
Fifteen months from the first sample to the final hide. More than two dozen tanneries. One significant failure that told us exactly what we needed to know. A partnership built on trust and the willingness to think without the constraints of tradition.
OLEÓ leather. From the Latin root for oil — oleo — the same root that gives us olive, that gives us the pressed oils that have colored and nourished things from within for centuries. The accent is ours. The meaning was already there.
A leather developed specifically for KIMIAS over fifteen months — oil wax, full aniline dyed, infused rather than coated in full grain, grade A hides hand selected from particular regions. The sheen you see is the oil. The color that shifts in the light is the aniline living inside the grain. The quality does not sit on the surface. It never did. It’s inside, not just the hide, but the development process.
That is Oleó.
