"When investing in a classic duffel (with a crossbody strap, of course), you don’t want to go too big. We like this one from Barbour, because it’s really only big enough to hold a well-curated weekend’s worth of stuff. Overpacking a much larger duffel will make the bag more cumbersome to carry. Plus, a smaller holdall like this is much more versatile: Use it as a weekender, as your carry-on, or as a gym bag. The eye-catching tartan will set itself apart but it’s still got all the convenient features of a handy duffel: plenty of pockets and an adjustable shoulder strap."
