Water and a pee bottle would be high on my list for hunting from hides. I carry my bow in my hand. 4-6 arrows. My gear gets tucked into my catquiver pack. That would include binocs, knife, radio if provided, lunch, snacks, reading material, tab, armgaurd, headnet, gloves, still and video camera with tripod, journal. Wear a windproof jacket for the ride out/in if your in the pickup bed as the mornings can be cool. I am sure there is something I missed and others should chime in to help.
