Gone are the days when all luggage was blocky and cumbersome. Many bags now on the market transform from business accessories to day-hiking tools with a few strategically placed zippers or tabs. While they won't replace your backcountry packs, these new bag designs are more than enough to let you squeeze a bit of adventure into a business trip.
We're currently testing one such transformer bag called the Osprey Contrail 22, which came out in the fall of 2012, and attaches to a rugged day-hike pack. The Contrail is basically a rolling carry-on with a nylon tab that lets you attach an optional backpack to it. Because the Colorado-based Osprey had its start in custom backpacks, the pack isn’t just some throwaway idea, but a carefully designed accessory that's burly enough to stand up to whatever you put it through.
