  • Main compartment features a drop pocket that secures with a hook-and-loop tab, a mesh pocket, a padded electronics pocket, pen sleeves and a secure zippered pocket
  • Cover flap overlaps the sides of the bag to block rain; zippered pocket on flap has moisture-shedding reverse coil zipper
  • External side pocket stows a cell phone, power cords or water bottle

  • Patagonia Half Mass features a topside carrying handle, reflective panels for visibility at night and a bike-light mount
