The Solo Urban Hybrid Briefcase is a roomy polyester briefcase that converts to a backpack or shoulder bag, all weighing less than 2 pounds. The padded, easily adjustable backpack straps can be tucked away in a pocket made for that purpose, and the padded shoulder strap easily detaches and stows away.
It’s incredibly versatile for a traveler who wants the most out of every bag. For a long weekend, this is all you need — the heck with a carry-on — and you wouldn’t have to compete for an overhead bin. It can slide under an airline seat while easily holding all a few days of clothes, plus an iPad and other small electronics.
