I've seen many trail/ultra runners wearing sponsored clothing. Their main sponsor, e.g(Hoka One One, Patagonia) would usually be the shirt, and their personal sponsors like Clif, Smartwool, Flora Health, and Vasque would be stuck on the shirt. I wondered if their sponsors were just sticker that the company put on their clothing for them, or they custom ordered it. If I was to be sponsored, am I able to make a custom sponsored shirt like this?
