Which size should I get?

All three sizes share the same 15-inch height and 11-inch width; only the length changes. The 20-inch suits a weekend or carry-on, the 24-inch covers a few days, and the 28-inch is for longer trips or two people.

Yes. It is full-grain water buffalo leather, the top layer of the hide, with a canvas-lined interior and brass hardware.

Does it have a shoulder strap?

Yes. It comes with an adjustable, removable shoulder strap and also has a leather top handle for hand carrying.

Monogramming is offered as a separate add-on, not included with the bag. Order it alongside the duffel if you want initials or a name.

Will it fit in an overhead bin?

The 20-inch size is the most likely to fit overhead; the 24- and 28-inch bags are better suited to checked travel or car trips. Measure your airline's carry-on limits before flying with the larger sizes.

How do I care for the leather?

Full-grain leather benefits from occasional conditioning and should be kept dry. Expect the hide to darken and show scuffs over time; that patina is the point of the material.
