I carry a 75 liter pack - that's the space measurement. I could not carry 75 liters of water in that pack, that would be over 150 pounds, phew! Maybe they fill 75 balloons the same sized as ones filled with a liter of water then fill the pack to measure its capacity. LOL

TOTAL WEIGHT IN GRAMS | 
30,710  | 
The total weight of the above list is: 30.710 kg which is equal to 67 pounds and 11 ounces. I have estimated this load based on a trip of 7 days, so that would be the heaviest I would carry. Also because some of my load is food, as the trip progresses, my load lightens by a kilogram a day.
My new Cabela table is not in that list. I would not be able to fit it in my backpack, and it's too heavy to bring on a long trip. I might not bring my air mattress on a warm weather trip, it's pretty heavy as well.
I have to give a lot of credit to my backpack, it's pretty amazing at distributing the weight and making this load comfortable to carry. I even took it on a 12-km hike to carry my water, lunch and snacks, as I don't like a fanny-pack style waistband cutting into me while hiking. There's a hip band that swivels, I can hike up the backpack higher and my hips take the weight for a change. There's a moveable chest strap holding the shoulder harness tighter in the front, I will put my hands on that to help carry the load also for a break. And I couldn't do any of this carrying without my trusty walking poles!
When I get home from my camping trips, my final carry is three flights of stairs up to my apartment. That's the only time I wish I had an elevator.
