BOMBER VAGABOND
What looks like a techy backpack splits into a 1,340-cube daypack and a 4,400-cube main hauler, carried as shoulder or side bag. In Iquitos, Peru, it all behaved like a comfortable 40-pound backpack, with load-adjuster straps and stiff back panel, as I traveled by boat and navigated muddy streets where no roller could go. Organization? You’ve got options: three side zipper pockets, two top-panel pockets, and a duffel compartment with separate zippered mesh sleeve in the main bag alone. And the daypack sports a pair of water-bottle holders, a zippered pocket outside, and a padded laptop sleeve. 5.5 lbs; mountainsmith.com
