I like a small back pack, I get kidded too, by I like having tools and comforts with me. The contents change all the time, generally batteries (GPS and flashlight), flashlight, extra compass, maps, 2 knives, brush shears, tracking tape (10 feet or so of the ornage ribbon stuff) candy bars, can of soda or water. one of them space blankets (never needed it, but weighs nothing and folds small, its there if I need it. toilet paper (never know) couple tie wraps for tags etc.. whistle, bullets, camera, gloves, water proof matches, FRS radio, cell phone. only about 4 pounds, dont notice it on my back, gives me a feeling of security.
