Collection: Pit-tanned, shrink-tanned steerhide

What is pit-tanning?

Pit tanning is a long process of tanning using a "pittank " which looks like a huge bath filled with tannin. (Normally, tanning is done in "drums" (large wooden barrels for tanning skins).

The tannin is slowly soaked into the skin in several tanks with different concentrations of tannin, and the skin is transformed from "hide" to "leather" by the process of repeated soaking in the tanks.

Pit-tanning is a time-consuming and costly process, requiring a lot of time and effort, but the tanning process is also very effective in reducing the burden on the hides and giving them a natural texture. However, the leather is not overloaded by soaking for a long time, and the natural texture of the leather is preserved.

Characteristics of pit-tanning

The tannin is soaked into the leather over a long period of time, resulting in a strong and durable leather.

As the leather ages, it becomes more supple and comfortable, and it develops its own luster.

The leather is tanned using tannin (plant astringent), so there are no harmful substances left in the leather, and the leather is environmentally friendly as it can be easily returned to the soil.

This is a leather that is worth growing up with its characteristic luster and bony appearance, with fibers that are packed with grain to the utmost limit to give it an impactful look.

This leather is fully tanned by soaking North American raw cowhide in a pit tank in Japan for about 3 months.

The leather is pit-tanned, and has a strong fiber luster and a bony look.
(The original thickness of the leather is 3mm, which gives the leather an even stronger graininess.)

) Since we use a natural grain to create the grain, each piece of leather has a different appearance.

The leather has a firmness at first, but as you wear it, the luster will increase and it will become more comfortable to your body.
