The Columbia Drifter II Backpack is a tough, super-versatile daypack, featuring Columbia's Backdraft ventilated back panel, a padded, zip-closed laptop compartment and an Omni-Shield water-shedding exterior to protect the packs contents from foul weather. The sternum strap with rescue whistle and removable hip belt keeps the fit complete while the compression straps stop you gear from shifting.
