New: the old tanning process

VoVo leather

Our main source of raw material is wild red deer from Switzerland. As we do not use breeding stags from New Zealand, wildlife marks such as scars, skin folds or minor injuries can be expected, but they give our leather its unique look.

In the near future, we start offering the finest and most breathable leather from deer, wild boar or Estonian elk.

Our leather is “organic”, because there is nothing more “organic” than a leather from red deer that has lived a long and happy life in the wild and been hunted sustainably. Despite that, the official organic label (like those of Bio-Suisse) is only awarded to agricultural products like cattle or calves.

Pure Gold in the world of leather: Valonea oak tanned red deer skins made by Zeller in Steffisburg, Switzerland.

We want our precious raw hides to stay as natural as possible. Therefore, we refuse to use chrome or whatever chemicals during the pre-tanning and tanning processes, as well as any synthetic materials for dying or surface sealing. Our VoVo leather is 100% treated with natural tanning agents. For this reason, our customers can wear our shoes and clothing in good conscience and without any health concerns, even barefoot or right on the skin!

Shoe-maestro Silvano Sassetti enjoys the smell of  leather that will be worked into the first familiy of Cervo Volante shoe prototypes.


VoVo smooth leather

The VoVo smooth leather is produced in small tanneries in Switzerland. Through close cooperation with the Zeller tannery one can fall back to the traditional barrel tanning and the use of European tanning agents.

After several tests and continuous optimisation, beautiful colourfast and water-repellent deer leather is produced within about 2 months.

For the tanning process, we want to be sure that only sustainably harvested plant extracts are used (for example, hand-collected oak fruits from Turkey). When possible, we leave our leather in natural shades, i.e. those directly gained from the tannic extract. For further colours we are developing the application of natural dyes.

Jürg Zeller’s first words when he saw the metamorphosis of the wonderful VoVo Leather into the shoes were: „Dä würeni de grad näh..!“ (“This I would love to have for myself …”)

VoVo velvet leather

The incredibly soft VoVo velvet leather is one of the finest among suedes and nubuks. Our red deer hides are tanned exclusively with codfish oil by our German partner Kolesch, according to ancient tradition (old-sage or old-chamoise). The oil tanning agent is beaten into the skin with heavy wooden mallets.

Kolesch in Biberach, Germany is one of the last tanneries worldwide that practices the old chamoise tanning method, to achieve a very soft smooth leather (nubuk).

Thanks to exclusive use of environmentally friendly substances, after depilation the deer skins will be rinsed in a creek. Only wood dyes are used for colouring and skins are hand-brushed on the hairy side of the leather. The entire tanning process takes almost a whole year, during which the tanner manipulates the leather about 300 times… Pure traditional and ecological craftsmanship!
