Enjoy color fading of denim

The ideal coloration is achieved by adding a secret indigo dye, and repeatedly dyeing the threads and exposing them to the air to oxidize them.
The timing is fine tuned to suit the weather each day.
The culmination of these processes results in an indigo blue and beautiful edging.

It has a jeans-like design as an hommage to denim

We used Tochigi leather from one of the world’s finest tanners.
The case leather, which is also used on the hip labels, on the jeans, brings an oil-like depth, which allows you to enjoy the aging of the fabric, as you would with denim.
We also created an re-formed the Kaihara Denima brand logo to create an original engraved logo.
This special design is only available on our straps.
Further, the holes used to fit arm size contain stainless rivets.
They are the same as those used around jean pockets, for a detail only found on denim items.

Exclusive logo embossed on Knot straps

The Kaihara Denim brand logo is also a unique, redesigned logo exclusively for this piece. This special re-imagining of the logo is available only in Knot straps.
