The “tactical” pants worn by law enforcement officers have slowly evolved into Tactical Internet Pants, worn and loved by geeks:
There’s a whole background here that others have told better than I, but the short story is that these pants were originally designed for climbers. Then the FBI discovered them, and the company started selling to the police and fire departments hard core. Now, the same things that made them popular to the emergency services folks are getting them discovered elsewhere. They are really well-made clothes that are designed to fit a wide range of sizes, and will help you carry and use all the gadgets you need to take with you. Plus, you kind of look like Indiana Jones when you’re wearing them. Kinda.
