Impact Jackets has been selling inflatable safety jackets for the past few years at a cost of nearly $500 each. They’re a great idea in theory, but how do you know if they’ll work? Well, a Baltimore man got to find out firsthand, as he was thrown 100 feet from his motorcycle after being cut off in traffic. The bag inflated as advertised and saved him from extensive injuries. He walked away with some sore ribs and a broken thumb, but medics on the scene said it would’ve been far worse without the jacket.
