All leather directly managed series of "POTENTIAL" series, a flagship model of Master-Piece.

The original leather skin is carefully selected and used domestic stear. After chrome tanning, a 3M waterproofing agent is put in a tyco at the time of dyeing, and waterproofing is penetrated into the leather fiber.
The waterproofing agent is soaked in the back of the fiber, so it will continue to prevent the water from entering not only from the back of the leather, as well as the side of the scratches.
Because a large amount of special waterproof oil is penetrated there, it is finished in a supple and soft touch. The surface is also finished so that the texture is fine like a kip.
It is an extremely soft and ultimate soft smoothing that cannot be done without a good balance, such as tanning, dyeing, and oil mixing.
This leather is a waterproof, oilproof and antifouling leather that has passed the "Scotchgard" monitoring test (it is hard to remain). This monitoring test is done by cutting the surface, so it does not diminish as you use it.

Outlast is used for the body and back body. This is a micro capsule containing Outlast at an Outlast -designated coating factory developed for NASA absorbs excess heat from the body and releases the accumulated heat when the temperature is low. Because of the work, it has a function to maintain a comfortable temperature (31 C ~ 33 C).
In addition, the original jacard with Master-Piece logo is used for the lining.
