A ‘pro tip’ for evaluating the quality of a piece of gear is to look at the small details, such as zippers and stitching.
YKK is short for Yoshida Kōgyō Kabushikigaisha, founded by Tadao Yoshida in 1934.
Today, the YKK Group makes roughly half of the world’s zippers.
Over the following decades, YKK grew from being an imitator to an innovator, creating the world’s first nylon zipper, polyester zipper, concealed zipper, and the world’s smallest zipper.
YKK zippers were used in the spacesuits that went to the moon in 1969.
While YKK avoids the media, the company takes the Cycle of Goodness so seriously that it produced a 10-issue manga series that explains it in detail. (YKK also made a zipper-themed anime.)
YKK doesn’t share many technical details, but Ororo shed some light on what makes YKK zippers so good:
- Square-tooth technology that ensures smooth, reliable zipping
- Self-locking design that keeps the zipper from unzipping itself
- Self-lubrication that keeps the zipper working well
