Sorry... Didn't see your question.
To answer your question, Maybe... Although I will tell you that this has been tried three times before, with very little results. We can talk about it, we can post, we can try all kinds of things, but until some body comes to me with a minimum of a 10 jacket order paid in full, I can't see it happening. But it you want to try, go ahead. I have just found it very difficult to get people to comment to a group purchase.
Also to answer your question, yes; our poker run jackets can come with a collar, but unless you're wearing a helmet it will not do you any good. They do come in just about any color and can have stripes and logos (embroidery). Let me know what you come up with.
