Having been in the unpleasant position of getting hit by a car while riding a bicycle, I can appreciate the existence of what seems a rather crazy product: a jacket with build in airbags! Impact Jackets manufactures these for motorcycle and horse back riders; I wish they had a light version for cyclists, at least for the winter because who wears anything more than a t-shirt during the summer? The jackets are a bit expensive at $500 but compared to preventing you from shuttering your bones and even saving your life, it is a small price to pay. Some guy in Baltimore already owns his life to one of these jackets.
