Charles from Bonnie & Clydes (1751 W. Division Street / 773-289-7966) in Chicago recommends BillyKirk's No 165 Day Travel Bag and I couldn't agree more.

Our day bag is our best selling travel bag. It's the perfect size for light trips, the gym or use it as a briefcase. The one featured is made with an 18 ounce natural duck canvas and top quality leathers for the trim. The adjustable strap is now made with 100% leather. Two interior pockets. 6 dull silver bottom feet. Comes with hand-stitched luggage tag. 16" frame. Oiled and edged leather. Made in the USA.

If you're not familiar with the line, check out their site. It's two brothers who design leather goods that they have made by Amish in Pennsylvania, which means -- unlike certain countries half way around the world that deliver lots of cheap goods to the US -- superior quality. The Amish don't F around.

The line can be found at Barney's, Fred Segal, Odin, Bonnie & Clyde's, Oak, Unis, Aloha Rag, and many many more shops worldwide. Check here for the full list and here to see more styles of bags from the line. I want one in each style please.
