Recommend the green one...
Love this bag. All the basics you need. Some great front slots in the front zipped pocket for organizing. Side mesh holds all drinks well. Especially love the two top zipper pockets for holding sunglasses (soft lining) and other personal items (in the nylon lined pocket). Also, interior laptop slot is padded and is perfect for 15-17" laptops.
In terms of comfort, it has great padding for the back and straps. Ergonomic fit when you're wearing it.
Also, bought the green color and it pops. Has the newer logo embroidered (not like the green one pictured). Also, has a better color scheme than the green one pictured. There's more dark grey (i.e. mesh on the side is dark grey and all the white has dark grey contrasting lining next to it).
