Similar to what Karthik said, a hoodie sweatshirt
like this but with the FIRST logo on it (and perhaps offered in both dark and light colored versions?).
I like
this shirt, could you offer a long sleeve version as well?
Oh, 1 more idea, how about a mousepad?
Great job LOGOLOC, the store is great. Like Karthik said, thanks for asking our input, it means a lot.
