There's no reason to be carrying around a big ol' messenger bag all the time unless you have a laptop or other hefty items that need to be with you. If you just need to carry some essential stuff — magazines, work documents, wallet, passport, camera, etc. — the Varick Nylon Flight Bag from Coach ($150) will do the job in style. It's got a zip-top closure, an inside zip pocket, back open pocket, and leather trim that compliments the weather-resistant nylon. It measures 8.25 (L) x 10 (H) x 3.5 (W) and is also available in dark khaki.
