Our crew’s packs seldom weight 36lbs fully loaded getting on the bus with two quarts of water and three days of food.
Scouts’ packs are always lighter than the adults’. They generally have newer lighter packs, smaller lighter sleeping bags, use Z-rest sleep pads, smaller rain gear, need less layers, and carry less moleskin and such so tend to be muck lighter.
Mine is usually one of the heaviest packs at 36 to 38 lb. fully loaded. Dry with only my gear it weighs 23 lb.-13 oz.
