The Solo 15.6-inch Urban Hybrid Briefcase is a roomy polyester briefcase that converts to a backpack or shoulder bag, and weighs 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. One large cargo area, with two padded dividers, can hold your laptop, iPad, Kindle, etc., while still accommodating plenty of work-related files. Two exterior compartments can take smaller items such as a passport, a phone, and even a weekend supply of socks, underwear, and toiletries. The briefcase handle has magnetized snaps, a refreshing change from Velcro. This is the perfect "personal bag," as the airlines call them. That means it's not a checked bag or even a carry-on. I know today's plastic can wear like iron, but the buckles and connectors are made of plastic, which can give me pause. But metal fittings on bags are heavier and pricier.
