I have the Urban Go Bag in Coyote Tan and I have used it for a year commuting to work. It has a lot of space in the main compartment. I have a 14' Laptop, my lunch, first aid, extra food supplies, rain poncho, electronics and have room to spare. The side pockets are great for a water bottle and my travel coffee mug. The front pockets are good for id badge, pens and anything you need to get to quick. My only issue is the thin liner between the main and front pocket came apart at about 6 months at the stitching. I moved the items to a Maxpedition EDC Pocket Organizer and that solved everything. I highly recommend this if you are looking for a large pack that has room to spare.
