all of the sellers on ebay look legit and i dont think this bag has been faked yet, though i am sure the fakers will catch on and start making them in the future.
did you guys read the description? the lucky *&$ won this bag in a radio contest!
i think it is real too. i've seen it in the store. it's a pretty big bag, not for everyone and it retails for 850 so heck i'd take the 500 too if i had it and someone wanted to pay me that much for it.
