Why It’s CoolFirst, those spins: a padded pocket with a headphone port for tunes, on the front of the 4,200-cubic-inch bag; on the back, metal grommets through which you can thread a cable lock, and, on the bottom, a pull-out, seamless rain cover. » Most convertibles are weak in backpack mode, but I wouldn’t hesitate to tackle a multi-day trail hike with this one. A full harness, adjustable for torso length, zips out of the back panel, which incorporates a framesheet for load support. » A backpack-style sleeping-bag compartment can hold a bag or anything else you need to isolate. A detachable daypack, with ports for hydration and music systems, clips onto the bag and snugs, joey-style, atop the front mesh pouch.
Hmmm . . .The daypack rides a bit loose inside that front pouch.
