Great size for getting to and from work each day -- fits my 14" macbook pro with room to spare, and there's plenty of room inside the bag for my charger, a hoodie, etc. without there being a huge amount of space that would make the bag bigger. I like the small size. I put a limited number of things like car keys, sanitizer, lens wipes, in one of the zip pockets. I'm not someone who needs 15 differently-sized and shaped pockets to organize all my stuff. This would not be good (by itself) for you if you're expecting that. I wouldn't remember where things were in that sort of setup!
The bag looks beautiful. The blue color I got is stunning, and the materials (all fabrics, zippers, etc) are super high quality.
The clean lines and simplicity of the design means that there's no outside water bottle pocket, which I do miss a bit, but I've just been putting my thermos inside the bag and it hasn't been a bother. Tradeoff for the clean look.
I took the bag on a short overnight trip and it worked fine for me, but it's not that big and also only has a few zippered pockets other than the main one, so it's not ideal for overnights or as a travel bag.
Overall, beautiful, high-quality, but very very simple and not very big. Works great for me!
