Would this be a decent package to use for hiking through the Appalachian Trail this summer?

I want a packet of light, but also large enough to Carry All essential. Know of any good ways to test water is perfectly well that you can still walk in the rain? Thanks

Osprey, Gregory, Mountain Hardwear, Arc Go-Lite "packages teryx all do well. I `d go with something lightweight, but that can hold about 30-40 pounds. You can buy a backpack waterproof, waterproof package with a spray or wash the product, or you can buy a cover charge. The three are viable options.
