Generally staying above water is the goal for, really any point in your life with one exception: When you’re swimming. Then and only then will you want to dive below the surface. Still, that being said, there are times when you will need to quickly surface. The Kingii is the wearable that helps you rise to the top (of the pool) quickly.

This wearable goes around your wrist and is to be worn anytime you’re engaging in water sports that you wouldn’t wear a lifejacket for normally. This device lets you deploy a balloon to help lift you above the water, quickly, in case of emergency.

It can hold up to a 285 lb person and is refillable with extra cartridges. It comes with two refill cartridges to get you started but if you pick this up, hopefully you’ll never have to use it. It’s a good thing to have in emergencies and can help you pull yourself out of an overwhelming situation. The Kingii Wearable is $89.99.
