Bombora makes personal floating devices (PFDs) which is a new name for life vest, so you can bring along some safety when out on the water.
They offer styles for kids, adults and pets. We like the Wanderer Belt Type V in the Rasta design that is ultra-slim and lightweight and of course U.S. Coast Guard approved. It fits nicely around your waist, has a pull-cord handle to inflate it, a zippered pocket, and a D-ring so you can attach some other gear.
