I have the Stealth Premier 22" from Luggage Works. I probably overpack, but it has worked out well. I have squeezed it into the overheads on the E170 and old 737s, but opt for the gate valet when I can get it. It holds 8 days of socks, briefs, and t-shirts, along with 3 work shirts and trousers, sneakers and casual shoes, jeans, and three casual shirts. I carry jackets on the outside. Easier to pack when everything is clean.
