Your skin absorbs what you wear.
Conventional activewear is built from synthetic materials that have been detected at harmful levels in sports bras and leggings from the brands most of us wear every day. The natural alternatives on the market solve the chemical problem but fail the performance test — leaving you in soggy cotton halfway through your workout.
We are building the third option. Certified non-toxic, natural-fibre, performance-engineered activewear for women who train seriously and refuse to compromise on either.
Our Story
Oreeve was built out of necessity.
While navigating my own fertility journey, I began researching what I was putting in and on my body. I changed what I ate, what I used on my skin, and then looked down at the leggings I trained and lived in every day and realised I had ignored the thing closest to my largest organ — my skin — during the moments my body is most absorptive. What I discovered changed everything — BPA detected at more than twenty times the safe limit in the sports bras I owned. Microplastics found in human blood, lungs, and placental tissue. Chemicals that migrate from synthetic fabric into sweat-moistened skin.
I went looking for an alternative. What I found were two categories: high-performance activewear built from the very materials causing the problem, and natural-fibre brands that solved the chemistry but failed the moment I pushed them through a heated yoga class or a long run. Soggy cotton. Lost shape. No compression. No option.
So I built the third one.
My background is in ERP consulting — three years working across retail and manufacturing operations, learning how products move through supply chains and where the decisions get made that consumers never see. What I am bringing to this is the discipline to research rigorously, the process knowledge to ask the right questions, and the refusal to launch until the product meets the standard I would hold anything to that goes on my own body.
I am Jennifer. I am a yoga teacher, a runner, a health enthusiast and a woman who decided that the clothes I train in matter as much as the training itself. I built Oreeve because I had to. I am sharing the whole process — the research, the decisions, the failures, and the progress — because you deserve to know exactly what is going into what you wear.
Welcome to the beginning.

Our mission
We engineer activewear that is as technically precise as it is biologically safe — toxin free, beautifully designed, high-performance gear.
At Oreeve, we bridge the gap between minimalistic elegance and radical transparency. Because the safest activewear should also be the most beautiful.
One set. Hot yoga, Pilates, half marathon, coffee after. No trade-offs.
The Name
The name reflects where I come from. I grew up in Scheibenhardt — a town split between France and Germany — shaped by French elegance and German precision. That tension is the soul of Oreeve. The aesthetic is considered and minimal, the engineering is uncompromising, and neither is optional. The name itself comes from two French words: orée — the edge of the forest, a threshold — and sève — the sap that moves through living wood.
This is what Oreeve stands for — the edge of something new, and the life that moves through it.
Our Material
We are in active development. We are not ready to reveal exactly what we are making yet — but we can tell you precisely what will never be in an Oreeve garment, and the standard we will not fall below.
What we will never use
Polyester, nylon, and acrylic
Petroleum-derived synthetics that shed microplastics with every wear and wash, persist in the environment for hundreds of years, and have been detected in human blood, lungs, and placental tissue.
Conventional elastane (spandex / Lycra)
Processed with chemicals that leach into sweat-moistened skin. Independently detected at harmful levels in major activewear brands — including the ones most of us own.
Organic cotton as a performance fabric
We respect brands that use it. It solves the chemical problem. It does not solve the performance problem — cotton absorbs and holds moisture, loses shape under sustained sweat, and has no natural antimicrobial properties. A legging that fails in a heated yoga or Pilates class, a sweaty workout or a long run is not doing its job, however clean its credentials.
PFAS, BPA, phthalates, azo dyes, and formaldehyde
At any stage. Fabric, dye, finish, or trim.
The standard we hold ourselves to
Every fibre we use carries either GOTS certification or OEKO-TEX Standard 100 — independently verified to be free from over 1,000 harmful substances. We require a Transaction Certificate on every production batch, linking your specific garment to its certification. We commission independent third-party lab testing on every run and make the results available.
We will not make a claim we cannot prove.
Where we are right now
The fabric research is ongoing and the decisions are not yet final. We are holding ourselves to a standard that does not currently exist in the market at this performance level, and we are not launching until we get there.
We are documenting the entire process — the research, the testing, the decisions we make and why — in real time on our Instagram and TikTok channels. If you want to follow the journey as it happens and be the first to know when we are ready, that is where to find us.
