Master of Bishu

"It would be nice if it existed, but it doesn't exist in the world. So let's make it. That's the beginning."
Nori, the owner and chief developer of Teton Bros., and captain of the team, is an athlete who is a soccer player, skier, surfer, and even a former cowboy. Nori is a very straightforward person. He washes his dog carefully and mows the lawn properly. He's not one to be lazy. However, he doesn't use roundabout language and doesn't like to go to unnecessary trouble, so he's the type to take shortcuts where possible.

"Underwear made of sweat-resistant material is fine, but you have to wear something on top that absorbs sweat, right?"
I was talking about underwear suitable for outdoor activities. For example, if you make underwear out of a material that cannot absorb moisture, such as polypropylene, it is comfortable because it does not cool down due to sweat. However, if you leave it as it is, the sweat you produce will have no way to escape. Therefore, the common sense of layering today is that you should wear a second layer that is highly absorbent.
"But wearing two different outfits for the same purpose can be a real hassle."
It's certainly a hassle, but once you put it on you can wear it forever, so I thought that was fine. But Nori-san was different.
"I think it would be easier if those two cards were combined into one."
That's certainly true, but even though it's just a single piece of fabric, the side facing the body has the property of not absorbing sweat, while the outside has the property of absorbing sweat well and drying quickly. In other words, it has completely opposing properties on the front and back. Nori-san, that's literally a contradiction,' I said, laughing. But Nori-san, or more accurately, Nori-san's passion resolved the contradiction.

Bishu is the colloquial name for the former Owari Province, which is now the western part of Aichi Prefecture. It is one of Japan's largest textile production areas, having grown thanks to its proximity to the sea, which opened up maritime transport, and the ability to draw large amounts of water needed for dyeing and other processes from the Kiso River. Nori has visited the area many times in search of new materials and manufacturing methods, exchanging ideas with young engineers and sales representatives from many companies. Through these efforts, he has brought together the small steps of various factories and craftsmen, resulting in the creation of avant-garde fabrics that can be described as the product of their dedication.
First, the merino wool is treated with a special shrink-proofing process to enhance its hydrophilic properties while retaining the benefits of wool. This merino yarn is then used to knit a fabric that is highly absorbent and feels great against the skin. However, this process is where the real magic lies. By mixing merino yarn with polypropylene yarn during the knitting process, they have created a fabric with polypropylene on the skin side and merino wool on the front side. Let me repeat this so you don't get it wrong: it's not a sheet-like fabric. Although the yarn is knitted in a loop, the front and back have completely opposite properties. The result is an ideal base layer that has the comfort of wool but doesn't leave sweat on the skin side.

"I didn't do it. It was the work of the people of Bishu. So, to show my respect, I named the product MOB (Masters of Bishu)."
Nori says this, but I'm sure everyone feels the same way. If Nori hadn't been the captain, this dream-like project would never have come true. Technology and the latest materials are important, but here, teamwork is the foundation of manufacturing.
