I want to start running as part of my commute.

I need a backpack that will carry my lunch, purse, water, and jacket. Maybe a shirt and pants as well. The backpack must not jounce around on my back, and objects must not jounce around inside the pack.

Running does not work with my current pack, no sir!

Figure I am looking for:
  • smallish pack
  • chest strap
  • hip belt
  • load compression straps
  • water bladder capability
  • reasonable water resistance


Anyone have experience with a trail-running pack that they just loved? Or conversely, that they hated with a purple passion?
