Our story

Fighting drowning is personal to us

Dear Friends,

I invented the Kingii Wearable because I had a very good friend who died from drowning. Even the most experienced swimmer can experience a water emergency, and my friend paid the price for being unprepared.

I learned that my friend was not the only one who needed something to save him from the dangers of water activities. More than 372,000 people across the world drown every year.

That is why I invented Kingii, the smallest inflatable in the world. Although this wristband cannot replace a life vest (read our security advice carefully), it can give you additional buoyancy. Please support us - we need you to spread the word to make the water a safer place.

Sincerely yours,

Tom Agapiades

Our story has gone around the world

We are  thankful that the Huffington Post, NBC, The New York Times, Wired, and many other international news outlets reported about our product and brought awareness to water safety.

(...) I was skeptical when I first took it out of the box and set it up on my wrist to test it during a recent vacation. The device seemed big and felt awkward when I first jumped the water. 

But after a few minutes of paddling around, I barely felt it. I wore it off and on while wake-boarding, jet-skiing and even swimming in open water for exercise.

When I lifted the lever, the airbag shot out just as advertised and pulled me straight to the surface, where I had to kind of wrestle it into position in front of me to keep my head above the waves. Once in that position, it provided more than enough buoyancy to keep me afloat. (...)
