Our logo was designed by professionals so good at what they do, that they came to the pitch with only one design.  They are also so professional that the logo came with a multi-volume set outlining the proper usage of the graphic vs the text, what colors it could be drawn in or on and such.  There were a lot of examples of poor usage which I am embarrassed to admit we might occasionally execute (check out the tumbling Tibør t-shirt).  This t-shirt however was handed down like the tablets from on high.  That's probably why it is one of our favorite.  100% heavyweight cotton. Plain back.
