Speaking of Walmart, the standard mens' nylon toilet kit with main zipper and zipper side pockets, for five or six bucks, makes a good pipe travel kit, both in terms of capacity and compartments, and more important, for looking inexpensive. The airport kleptomaniac will see it and assume all he would get is your deodorant and toothbrush and keep looking for something good. He won't think it is a firearm, jewelry, or anything with i.d.s or cards. You can use pipe socks for extra padding, and it will easily hold tobacco and accessories. It is not as satisfying as seeing a fine leather pipe bag, but a better bet for security.
