I would like to know if Doug is ever going to review various back packs in the future? It is one very important item for when you are in the wilderness as it carries all your gear etc. What do you use in emergencies? What do you use for day hiking? week long hikes? Expeditions? etc etc. It is a topic that greatly interests me as I would like to buy a multi-day Back PAck to hike with. It must be internal frame though. Thanks for your input in anticipation.
