While I don't like the feel of a backpack for any length of time, I am completely comfortable with a waist pack. I always day hike with a waist pack and got a slightly larger one that didn't have any compartments on the front for my long bike adventures. I bought a couple of plastic cases that fit into the water bottle holders on the waist pack to hold my tools and other small items.
