I like to combine hiking trips with caching and love my Osprey Stratus 18 daypack.

My water filter, a MSR Miniworks, always goes in my daypack along with a Camelback bladder and two Nalgene bottles. You can use the Nalgenes for mixing powdered single servings of sports drinks if you wish; they're easy to clean. If you're hiking near one of those picturesque mountain streams on a hot day, you can pump some cool water from it if your supply gets hot, or you run out.
