This is the OneUp, a compact, self-inflating life preserver that has a portable inner tube that inflates upon contact with the water. The tube is 20 times lighter than a regular life preserver. It’s easy to carry in a beach bag, backpack, or store on your boat or even clip right onto your clothing.
This is the Ploota, a tiny “airbag for swimmers” that has an inflatable collar that activates when it detects an emergency in the water. If a person is submerged in the water for over 30 seconds, the Ploota’s integrated floats inflate with CO2 and bring the potential drowning victim to the surface.
