I don't see any info about the T-shirt on the event web site. Design? Fabric?--cotton or technical (guessing cotton if it doesn't say otherwise)? Didn't see anything about price either until wading through the actual registration process.
After scrolling down the page I discovered it's the same image as in the upper left (the Facebook "profile" image) ... green and blue on what appears to be a light green background.
The image down the page includes the text, which the profile pic does not.
Notable (compared to previous shirts) is the absence of "Georgia Navigator Cup" -- and presence of "Orienteering" (!)
Edit: I guess I spoke too soon...
