Full vegetable-tanned leather finished using the traditional Vacchetta method.
Uses "tea-core" double-shoulder leather tanned using the full vegetable-tanning method at Conceria 800 in Tuscany, Italy, and crafted via the traditional Tuscan *Vacchetta* process.
This leather is pit-tanned over time using vegetable tannins and slowly infused with neatsfoot oil, resulting in a texture that is firm yet smooth and feels as though it clings to the touch. Featuring a "tea-core" finish achieved through dyeing, it allows you to enjoy a rich, distinctive aging process as you wear it.
This leather comes from a tannery that embodies a blend of history, tradition, and innovation; they use raw hides from the Alpine region—where animals are raised in a stress-free environment—and demonstrate a meticulous commitment to both the tanning process (adjusting the blend of quebracho, mimosa, and chestnut tannins according to the leather type and color) and environmental responsibility.
A "tea-core" double shoulder leather, fully vegetable-tanned at the Conceria 800 (Ottocento) tannery in Tuscany, Italy.
Using the traditional Tuscan "Vacchetta" method, the leather is pit-tanned over time with vegetable tannins and then slowly infused with neatsfoot oil.
It is characterized by a firm yet smooth texture that feels as though it clings to the touch. Thanks to the dye-based "tea-core" finish, the surface color wears away with repeated use to reveal the brown base layer, allowing you to enjoy a rich, distinctive aging process.
The raw hides are sourced from the Alpine region, where the animals are raised in low-stress environments. Tanning is carried out using a blend of three types of tannins—quebracho, mimosa, and chestnut—with the proportions adjusted according to the specific type and color of the leather.
This leather is crafted by a historic tannery that upholds traditional manufacturing methods while also prioritizing environmental considerations and innovative craftsmanship.
