Have your safety back up strapped around your waist, with you at all times in open water. This PFD (Personal Flotation Device) is designed to be small and out of the way, yet right there and easy to use if you need it. It’s the best choice for athletes and recreational enthusiasts who want to wear a flotation device without the restrictions of a bulky life jacket. By pulling the cord you activate a 16gr. CO2 cartridge that fills a nylon tube in seconds. This gives you a life preserver that you can use for yourself or hand it to another person that might be in distress. Because the CO2 cartridge is replaceable and there is an oral valve, it can be used over and over again. For open water training or just playing around, use the oral inflation tube and save your CO2 cartridge for an emergency. It’s classified as a TYPE V – PFD and recommended for those at least 16 years or older, with a waist size 20″-44″.
