I normally use a TAD EDC bag for my EDC Bag. But i try to keep my work bag seperate since I work in a secure area. I want to keep my TAD bag locked in my car at work but have a messenger bag or laptop bag to keep enough items in that if need be will get me back to my car. I have been looking at several options and like the vanquest envoy. My laptop is 15 inch. I dont want something huge like the Envoy-17. I would prefer the Envoy-13. however, it doesnt seem to support my laptop size. Does anyone have any recommendations for a good messenger bag or laptop bag that is not overly large or overly high priced but durable?
