I have owned my camo/black Citizen Chrome messenger bag for over three years, and even after all the beatings and weather to which I have subjected my bag it still looks new. It is completely precipitation-proof while having Honda Accord-like trunk space and looking stellar. I would not trade this bag for any other on the market.
I have fit the following in this bag (one is fictitious, you be the judge of which one that is, but the rest are completely true): a week's worth of groceries; my 15" laptop, U-lock, and three university textbooks (the big ones); a week's worth of clothes (it was for vacation, I swear); an Xbox 360 with two controllers and six games; my little sister.
