Sustainable Leather

Our premium quality leather is tanned without the use of harmful chemicals. Our tanneries use special tanning processes to minimize environmental impact. We choose to work with naturally tanned leather, because leather is a natural material and we believe in using it as such. An O My Bag will age beautifully, deepening in color and softening with time.


Our leathers are tanned without the use of harmful chemicals, like chromium, heavy metals, formaldehyde, short-chain chlorinated paraffin, volatile organic compounds or alkyl phenol ethoxylates. To verify this, the leather is tested by independent laboratories. Instead of harmful substances, vegetable tannins are used in the tanning process. Research has shown that a significant part of the environmental impact of leather occurs in the manufacturing process. Therefore, it is not only the chemicals used in the tanning process that should determine how eco-friendly the leather is. Accordingly, water, wastewater, air emissions and energy use are responsibly managed at our tanneries..

We do not use any synthetic materials that are called vegan leather alternatives. We believe that using eco-friendly tanned leather is currently the most sustainable option to produce bags that can be used for a lifetime. Hides and skins are a by-product of the meat and dairy industry. Transformation into leather is the best use for those hides. Leather is a high quality material that is very durable and – unlike other materials – becomes more beautiful over time. Alternatives to real leather are mostly made from PU, PVC or other composite microfibers, which produce many harmful toxins in the production process and don’t fully biodegrade. Moreover, these alternatives will never last as long or age and develop over time as leather does. We make an effort to design timeless pieces that you can carry and cherish for years.
