Thurston is a retailer who contracts with Vanson, Aero and Thedi leathers. They originally were very involved with the motorcycling community in Seattle, under the Insurrection company moniker. You could purchase and customize a full race suit, etc and one of the founders was in fact a track rider. These days they are more casually focused (I believe).I have no experience with Thurston and prefer to deal directly with Vanson. My experience with Vanson has been satisfying. They are not fashion jackets. I like to support support small American businesses when I can so for me it is win-win, especially since they are involved in the motorcycle community. I don't know where Thurston stands.
