If you’re into aquatic activities the best wearable accessory for you could be the Kingii. It’s a compact and easy to use personal flotation device that you wear on your wrist. In case of emergency, pull its lever and it’ll help you stay afloat.
The Kingii uses a CO2 cartridge to inflate the bag. Once filled up, the bag can carry up to 275lb. and stay afloat for over 48h. The cartridge can be used only once; each Kingii comes with two cartridges, and you’ll be able to buy more from Kingii’s website after it launches. As for the bag, you can fold it back inside its compartment to be reused. It also has a built-in compass and a whistle.
Pledge at least $69 (USD) on Indiegogo to receive a Kingii as a reward.
