Knowledge: The original multitool.

There are many things to consider when you are taking stock of your camping equipment or making a holiday wish list: Titanium tent stakes, high tech stoves, ultralight air mattresses or sleeping pads, backpacks with more features than a luxury car, new boots, compact water filters and much more.  There are many ways to improve your comfort on the trail or simplify regular camping tasks with additions of new equipment but don't forget the most important thing, knowledge!  Keep your skills sharp and be prepared.  Knowledge does not add any weight to your load and is the original multitool.
