The Mystery Ranch Urban Assault Pack is a 21 liter backpack for everyday use, from the city to the trails. When exploring the urban sidewalks, moving from home to work or school, an interior sleeve Fits up to 15" laptops. The bag can be accessed via the 3-zip design, so you can grab the rain jacket you stuffed inside in a jiffy, or locate the snack you hid in there before stepping into that meeting.
The 500D Cordura fabric is crazy-durable, so tossing it underneath your desk won't damage it, and neither will a tromp through the woods. Keep small items from getting lost at the bottom of the bag by storing them within one of the two internal zippered pockets or the in lid.
