IST is a company founded in Taiwan in 1976, which is dedicated to the production of diving, swimming, snorkeling and freediving accessories.

When IST was first established, its main products were windsurf boards. As more connections with the dive community began to emerge, limitless opportunities opened up within this new market. IST began manufacturing diving boots as an introduction to the diving industry.

Later, the company began to release a wider range of diving equipment, including masks, snorkels, and fins. As pioneers in the market, they produced high quality at more affordable prices, which greatly favored them among diving enthusiasts.
