Yanko has some of the best ideas around. Swim Guard Vest is a vest that is worn like a Chest Harness with a bit more support around the neck, keeping your head afloat. The device is form fitting and I could see this being built into wetsuits in the near future. The really cool feature is the GPS that is built in. I can see Triathlons offering this as an options to those a little hesitant of the water, like theNew York City Triathlon, the Hudson can be scary.
