I’m curious about the start of ‘Double K’ and ‘SUBONE’

How did a person who won the top spot in one field come into contact with that field? Have you ever wondered how you go to top?

Now, if you are just starting out with freediving, or if you are new to ‘Double K’, you will get to know how people who enjoy freediving and are good at get into freediving in the first place and how to do it well.

Here, it's a video where you can look into the beginning of Double K

“When I was a salesman, I went into the sea because I didn’t want to hear the phone ringing.”

For CEO Sung-Jun Kang, the trigger for freediving was ‘stress’. 

I needed a break from the world, and I was more comfortable and completely independent than anyone else in the world for that time in the sea. 

I was drawn to the sea because I liked the serenity and serenity of the sea.

Representative Kang who has a natural entrepreneurial temperament, turned his hobby into a business and worked hard to become the best in his field. 

At that time, when I was a freediving hostage, I was exposed to freediving in the world market as a national freediving representative, 

and I dream of spreading the freediving culture in Korea through ‘Double K’.


Double K started as a sole proprietorship in 2014 and converted into a corporation under the name of ‘SUBONE’ in 2016 

by registering a patent for the predecessor of the smart suit and shoe-type foot pocket R1.

SUBONE means to become one in the sub and the best under the water.

SUBONE is a company name, and Double K is a brand name.

Double K will not stay in “Now”, communicate with divers, and strive to provide products and services for divers.
