As you'd expect from its pedigree the Backbone performs its basic functions exceptionally well. It's comfortable, and easy to slip on and off I might add, the large flap makes it easy to get stuff in an out, and it's unobtrusive when you're underway, all good things if you're a courier, commuter or just running errands. Those same attributes also work well when the pack is used for day trips, overnighters or even weekend jaunts. Frankly, I'm not that keen on carrying a weekends worth of laundry on my back, but the Backbone worked out nicely when I took a recent overnight trip on my dual sport bike. The Backbone worked out a lot better than the stylish, but small off-road style packs my buddies all carried.
