OneUp Self-Inflating Life Preserver

The OneUp self-inflating PFD weighs only .8 pounds and is 20 times smaller than traditional life preservers. Upon contact with water, the soda can-sized tube inflates within seconds to become a horseshoe-style floatation device.

Measuring 6.8” long, the MSDS- and CE-certified device comes with a waterproof cover to house the life preserver and a carabiner clip that allows users to attach the device to bags and belt loops.
