The Ortlieb Commuter City Daypack is a rolltop pack for weather protection in the city. Protection for your gear, not you. Load up your laptop or tablet into the padded sleeve, extra layers, lunch, maybe an extra pair of shoes, then roll the top at least 3 times and secure it. The straps are breathable while the backpanel features vent channels, to increase cooling on your ride into work. The sternum strap and waist belt stabilize it on your back, or remove them if you're just not interested.
So sorry, but only 4 items are allowed for comparison, so we're comparing the first 4. I blame the gnomes and so should you.
