The Mystery Ranch Invader Messenger Bag is a durable messenger bag for everyday work life and capable of the occasional plane ride. Built to be carried courier style, the pack slings over your back and stabilizes at the chest with a smaller, removable cross-strap. The large padded strap prevents heavy loads from cutting into your shoulder on the commute into work on the old ten-speed. The main compartment accommodates a 15" laptop in a padded sleeve and all your other stuff like headphones, lunch, extra layer or maybe a work file or two. Smaller zippered pockets secure small items like pens or pencils, plus your phone. See you in the office.
