I've only had this for a day but I'm loving it so far as an EDC work bag.
It easily holds my 15" Macbook Pro in the back-most laptop compartment, my iPad Pro 12.9 with cover/integrated Apple Pencil holder in the tablet sleeve, a phone, charge cables, "extras" wallet with loyalty cards, seldom used bank cards, RX & insurance cards, etc., a couple Field Notes notebooks carried in a Nock Co. case with three writing implements, bulky Oakley Fast Jackets in semi-rigid case, a decent sized medical trauma kit, a slim pack of baby wipes—and there's room to spare. BUT—and this is the great thing—it's got a really slim profile which makes an urban train or bus commute more pleasant, and which also works well to minimize your profile on the bike. And it looks cool to boot!
For the bike commuter, all of the above along with a set of business casual attire OR a pair of shoes appears to fit. Carrying both would likely work sans the trauma kit and a few other of the nice-to-haves.
• Plenty roomy for the daily work/life essentials but also forces you to consider what's needed (not a kitchen sink bag)
• Slim profile for easier mobility during urban commuting or while on the bike
• Sleek, modern appearance available in some pretty cool colors
• Appears to be robustly built of durable, weather resistant and easily cleanable materials
