What is a travel bag?
Summary
Built around airport constraints — carry-on dimensions, clamshell packing, and TSA-friendly laptop access. The best travel setups eliminate checked luggage entirely.
The full picture
Travel bags are built around the specific constraints of airports, hotels, and living from one bag for days at a stretch. The priorities are airline compliance (dimensions that fit overhead bins), packing efficiency (clamshell opening for full visibility), security (TSA-friendly laptop access, anti-theft pocket placement), and versatility (comfortable both on foot and in transit). The best one-bag travel setups eliminate the need for checked luggage entirely.
