This full-sized courier bag holds a day's worth of gear — from gym clothes, to reading material, to files for work. It has padding on the back and along the contoured base to protect the contents and provide structure. The main compartment features a drop pocket that secures with a hook-and-loop tab, a mesh pocket for visibility, a padded electronics pocket, pen sleeves and a secure zippered pocket. An interior, padded computer sleeve holds most 17-inch laptops. The front flap overlaps both sides of the bag to thwart rain; it also has a pocket that closes with a water-resistant zipper. An external side pocket holds a phone, power cords or a water bottle. Its no-slip shoulder strap is fully adjustable, and the stabilizer strap stows away when not in use. With a topside carrying handle, a reflective panel for visibility at night and a bike-light mount. Made of 600-denier 100% recycled polyester with a polyurethane coating.
