The Roller That Stores Smart: Timbuk2 Copilot

All the gear you'll be carrying is useful only if you can get to it when you need it. The 22-inch Timbuk2 Copilot is one of the best-organized rollers we've ever tested. Its clamshell design is divided by a mesh panel, which allows orderly access to all your stuff – even if the bag is completely full. [$225; timbuk2.com]
