TOM BIHN Western Flyer, Carry-On Backpack & Briefcase, 26L

The convertible backpack-to-briefcase design is what sold me, and it doesn't disappoint—switching modes takes seconds and feels sturdy. I've used it for a weekend trip and a work meeting, and the 26 liters held everything without feeling bulky overhead.

The 26L capacity hit the sweet spot for my weekender—fit perfectly under the seat and the three-in-one conversion was a lifesaver when I needed a proper briefcase for a client meeting. Strap padding made the backpack mode surprisingly comfortable even when fully loaded.

Took this on a four-day trip and the briefcase mode made airport security a breeze—no more digging through straps. The way it switches to backpack when I hit the cobblestone streets is honestly brilliant for the size.
