Contrary to some reviews, this bag's capacity is good. I can fit everything I need in here, which usually consists of a laptop, an ipad, documents, water bottle, umbrella, various pouches for organization, and some leftover tech. I can even fit a jacket and gym clothes in a separate sack if I overflow the bag and ride up the flap. This is a 15L bag, so it will most likely fit all that you need for the day, but not much more. I have a 22L backpack if I need to carry more. My use-case is quick access bag for daily urban carry, and this is perfect for that. The weight of this bag at full capacity is the most that I can comfortably carry. A 24L would be impractical for me.

The seatbelt straps, outer nylon material, and the inner lining feels durable. Adjusting the shoulder strap is smooth. There is a loop to organize the dangling shoulder strap. And the stabilizer strap is surprisingly robust. My 15" MacBook Pro fits perfectly in a well-padded laptop compartment. Overall I'm very impressed by the build quality.

Some reviews remarked that the material is stiff and compresses too much into the main compartment which reduces the usable space. I disagree. Stuffing the bag feels snug now but the nylon will break in and the pockets will expand. And as long as there are no fragile things in the main compartment (like food), the main compartment compression is a non-issue. You can utilize all the space as long as you're not afraid to actually use the bag and stuff it full.
