Toward the creation of the "Protecting Important Life" item

In recent years, while the natural disasters such as heavy rain, earthquakes, tsunamis, and the threat of new coronaviruses, such as earthquakes and tsunami start. Bag Brands Katsuyukikodama Paradiddle as a designer, felt the need for "life" as a single company in the fashion industry proposed a lifestyle, and started this project.


Live and survive to concept

There is also a region where the designer's hometown is concerned about the flooding of the river, and this time, we looked at the functions that correspond to intensive heavy rain and flood damage. In the event of a disaster, early evacuation is important, but if the bag is a life jacket (life jacket) in case the bag is encountered, it is a life jacket (life jacket), and this time, "I wish I had a good thing" The direction of life jacketed driver (waterproof backpack) is determined.

In order to produce a waterproof function bag, the wall stands in front of us. We produce a bag of "Katsuyukikodama Paradiddle" brand at its own factory, but waterproof specifications use a completely different molding method with general sewing technology. The molding method that does not penetrate the water is not sewing using thread and needle, but is molded by welding by high frequency welder = welding (hereinafter referred to as welder welding). For example, tents and floating wheels, household vinyl pools are also molded in this way. In addition, it was understood that the life jacket to be mounted on the bag is also shaped by this welder welding.

So we areStart a factory search for welder welding. There were no many companies found in Japan, and it was not possible to have an appointment from the viewpoint of production technology.

Such a time, the manufacturer will be appointed to the manufacturer that holds a large share in the production and sales of life jackets, and the meeting starts immediately. To staff membersThank you for your understanding of the concept of "Live and Survive (Live & Savive"Finally, the development of a backpack that finally combines a lifetime and a dry buckpack (waterproof backpack) starts.

The final sample was completed in 2021, repeatedly creating and correcting prototypes for several months.
