The Impact jacket is a new safety innovation for bike riders. IT provides a strong airbag cushion to protect the rider if he/she is thrown from a bike during an accident. It provides a much needed second line of protection after helmets. The video on the website give more information about the product. It costs $500 but I guess thats a small price to pay for a safer bike ride.
