We use YKK outdoor zips, reputed as the best zipper on the planet. YYK is renowned for their high-performance and non-corrosive qualities. The letters stand for “Yoshida Kogyo Kabushikikaisha” which, from Japanese, roughly translates to “Yoshida Company Limited.” Interestingly, the company makes half the zippers on Earth, which is more than 7 billion zippers each year.
