Clothing Arts, which specializes in "pickpocket-proof" pants and shirts, came out in April with these lightweight, stylish trousers made of "Nature-Like Nylon" that don't have bulky exterior pockets, but do have all the zippers and buttons necessary to keep your belongings where they belong. (The company makes a similar pair in cotton that are heavier and more like khakis.) According to the label, the pants are stain- and water-resistant. The same properties that make the pants wrinkle-free mean they don't hold a crease, so they can look a bit formless, especially at the bottom over shoes.
