Lost: olive green hooded shirt (jan 2009?)

I've been trying to find my favorite garb shirt, and think it may have gotten lost at the jan 2009 event.
It is a lightweight olive green long sleeve shirt with a keyhole collar (the open slit from the neck to the chest) and a hood.
I was staying at the guard's barracks that event, so it may have gotten mixed in with someone's gear accidentally.
thanks,
Zack
(no, not that one, the other Zack... the one with the long hair... Zack II maybe?)
