Now now, no-one's forcing anyone to buy anything. If FutureProof comes up with a great design and can guarantee a quality shirt (Hanes, Fruit Of The Loom, Jerzees, Gildan etc), I don't see why he shouldnt offer to make them for people. I highly doubt he's gonna make much money out of this, certainly not enough to justify the effort, so thats not the intention. He obviously wants to give people what they want. Its upto him to come up with something that people want.
I'm sure that when Scott comes up with the goods with an official shirt that people will want one of those too so it won't be taking orders away. (Right, people? that had better be true

).
Besides, I know how easy it was to make my own so rather than get one shipped from over there in the USA, I'll make another here if i want one
