You want a daypack, need a laptop backpack and a hydration pack. Three different Crumplers is one option. The three-in-one Yee Ross is the other. The flexible and compact Yee Ross holds a 4-litre hydration bladder or 13" laptop in a rear sleeve, your tunes in a centre zippered pocket, and your stuff-du-jour in a 13-litre general cargo space at the front. It also has dual external zippered side pockets for those things you want to keep close at hand.
The rear of the bag and underside of the harness both feature Air Mesh padding.
