Stashitware Travel Underwear endorsed by Bob Arno and Bambi Vincent . UPDATE May 2, 2012: I wore Stash it ware on the world's most crowded trains, trains so crowded you have to see them to believe it, and I have to say: I loved Stash it ware! I never worried about my cash, credit cards, and ID. It was perfectly comfortable to carry it all in Stashitware. And my stuff was quick and simple to get out and put back. They would put pickpockets out of business-and this blog, too. "If these were in stores," Bob Arno said, "pickpockets would become shoplifters to get them off the shelves." --- Bambi Vincent, Thief Hunter. 100% Polyester. Very light. Nice huge Pocket. Easy Access. Great for wearing around the house. Great for Women also if they fit. Can be worn alone. Not see through. No Fly for accidental exposure. Very Comfy.
