I have fallen in love with Duluth's Twill Presentation Jacket. The catalog picture above doesn't do it justice. It is just dressy enough to work for business meetings, but enormously versatile to wear for just knocking around. In the last month, I have worn it everywhere from going to the movies to staying two days in a swanky hotel in Morocco for business meetings, hiked part way up an 11,000 ft mountain, and slept on a long flight. As this implies, it is a dreamy traveler's jacket -- never looks wrinkled (it is treated to resist wrinkles and stains), is tremendously comfortable, and has 13 pockets including zip-up pockets inside the outer patch pockets. Enough space to fit a moleskine in an outer pocket, a cell phone inside, a wallet safely zipped-in, some pens -- and suddenly I don't have to carry a backpack when I am going out for a quick meeting. And credit where credit is due: I first spotted this jacket on Tim O'Reilly, and promptly copied him, though in a different color. (I recommend the khaki color.) Although the jacket comes in other fabrics (canvas and denim), I think the twill is far and away the most versatile.
