It's an okay bag. The size is great. The adjustment thing on the strap is a pain to finagle and is too easily accidentally undone. I wish the bag had an external pocket. There's velcron inside the flap which is really useful for quick getaways, but since there's no external pocket you can't access anything without making a Velcro sound. That makes this pretty useless as an alternative to a briefcase, but also increases the water resistant quality that makes it a good messenger bag. Would be so much more functional with just a mesh pocket outside to hold stuff you need quickly like a water bottle or rain shell.
