BDU Wallet

Nobody wants to carry a man purse, but if you need a few pens and papers and don't want ink on your shirt or your pockets stuffed with papers, BDU Wallets are really nice.  They're made to fit the side pocket of cargo pants, or attach to your belt, or just be carried in your hand -- some have iPod/cell phone pouches built in, too.

Are they're a lot cheaper than a purse.
