During the recent Wizard World Toronto Comic-Con, UD Replicas unveiled their new X2 Wolverine Motorcycle Suit – including leather jacket, pants and gloves as seen in X2: X-Men United. They'll begin accepting orders online in late April.
I'm not sure if they'll be ready for your San Diego trip, but you might as well start growing those mutton chops now. FYI - if you ever see me at SDCC dressed up as anything other than myself, I give you permission to punch me.
