Is Underarmor a sponsor of MLS? I could swear that I remember that they were a sponsor. I want to buy some tights for skiing & bicycling & I might as well support an MLS sponsor. But I checked MLSNet.com this morning, and I could not find anything about Underarmor.
I think they are an official supplier, but not a sponsor. Not sure of the exact relationship, but their press releases do show up when I do searches for MLS.
