I spend most weekends during the summer doing 30+ mile hikes through the canyons in the southern Utah dessert I can usually manage to never see another person. I carry a sleeping bag, pad, bivy, a titanium kettle, small stove, compas, map, small first aid kit, fire kit, water filter, a 10 leader water bladder, extra socks, para cord, climbing rope, headlamp, snacks and food, and a 6 inch belt knife. The water is always the heaviest my summer sleeping bag is rolled up with the bivy and is smaller than a standard nalgene bottle sometimes I add a harness to the pack but that depends on the canyon some require 100+ foot repels
