Osprey makes awesome EDC capable packs,

I like my modified Talon 14, been using it daily for last 2 years around the 5 boroughs on NYC!
Very comfortable with a moderately roidges/cushioned ventilated back panel.
Carries all my gethome stuff, snacks, small HVAC measurement tools, engineering drawings, comes with a hydration bladder (i removed mine and use that area to store ppe and tools.
