新宿旅行袋

Took this on a four-day work trip and it slid under the seat in front of me, no gate check needed. The dual carry handles make it easy to grab off the belt, and it holds a laptop plus two days of clothes without looking bulky.

The briefcase-to-duffel conversion is what sold me — carried it as a briefcase through the airport, then unzipped the sides and slung it on my shoulder for the walk to the hotel. Handles the laptop plus three days of clothes without looking bulky.

Took this as my only bag on a four-day work trip and it handled both the laptop-and-blazer days and the casual evenings without looking out of place. The hybrid shape really does cut down on what I need to carry.
