I got this bag because I wanted to down size from the 40L REI backpack I've been using for work for the past few years. I've been looking at this and the Buran 3 but the redesigen Citizen with the front pockets won me over. It's durable and I see many years of use out of it. I knew that going from a 40L to this 24L would greatly limit what I could carry but that was the point in getting this bag. However, I think if it were a bit bigger it would be perfect (for me) either 27L or maybe 30L. I keep my 48oz Nalgene wide mouth water bottle, my padded luch bag and a 12oz can energy drink and a flannel in it. That's it, not really a lot but that seems to be the capacity. If I want to put in a sweatshirt instead of the flannel the flap will not close enough to use the velcro so luckily it has the two buckles. The two front pockets are nice but they are pretty flat so you're limited in what you can put in them, I thought they were more spacious than what they are. In one pocket I have my Czech pouch" that contains an Anker power bank, a charging block for the wall, 2 cords, 2 pairs of earbuds and a few pens. The other pocket has a eyeglasses case, keys for work, and a few smaller random things. I plan on getting some kind of pouch that I can atatch to the strap for storing a few smaller things that take up space in the pockets. The padded part of the strap that goes over your shoulder seems to fit (me) oddly. The buckle for the under arm strap is almost too high up on the shoulder…
