I have had this idea in my head for some time but dont know where to get started. I want to produce a highly technical riding jacket that I could design and then presell to other riders. This would similar to the heroic racing group buy where people could view a prototype and then sign up for the group buy. The more people that buy of course the less per unit cost and more a of a commitment that could be made to the manufacturer. This would also allow for custom sizing which for jackets always seems to be a issue. The problem of course is I have no idea were to find a manufacturer that would work with me and could produce a prototype. I dont suppose anyone here has any trade secrets they'd be willing to share?
