Carl Friedrik Hero

Leather, the natural, Italian way

Grab the attention on with a little sub-heading that looks nice.

We exclusively use full-grain Vachetta leather, sourced from a single family-run tannery in the heart of Florence. A by-product of the meat industry, this type of premium leather is natural, durable and rich in complexion.

While today’s leather industry is highly mechanised and reliant on chemicals harmful to the environment, our tannery still practices the ancient, labour-intensive art of vegetable tanning.

This method utilises natural vegetable tannins — found in tree bark, leaves and roots — to turn animal hides into leather. Master artisans spend a lifetime perfecting their tannin blends, drawing on knowledge passed down through generations.

As it ages, our Vachetta leather softens and becomes increasingly supple, gradually exhibiting a new complexion. The natural ageing process is known as ‘patina’ and is a hallmark of quality.


A commitment to sustainable manufacturing is at the core of Carl Friedrik. Aside from the desirable physical properties, we embrace vegetable-tanned leather because it will naturally biodegrade. Unlike chrome-tanned alternatives that spend centuries in landfill sites and cause microplastic pollution.

Forming part of the Genuine Italian Vegetable-tanned Leather Consortium, our tannery embraces sustainable and socially responsible practices. Such as repurposing waste products into raw materials valuable to other industries and only obtaining tannins from renewable sources.
