FOUNDED 1976

Company founded in Taiwan. Siblings Irene, Stanley and Tony Lin join together to form IST. Named after their combined initials, the company symbolized a community effort to work together toward a better future.

When IST was first established, their primary products were windsurfing boards. As more connections to the diving community began to emerge, boundless opportunities within this new market opened up. IST began manufacturing diving boots as an introduction into the scuba diving industry.
