It was impressive. I had everything, too: my kitchen, winter sleeping bag (!!!!!), shelter, water filter, rain jacket and bottoms, insulated jacket..... my whole kit. I had been hiking already for 5 months, though, so I knew how to cut corners and what risks I could balance. (Thru hikers often carry long underwear tops and bottoms, but no 2nd set of clothes.) 35L is the same I would take for a day hike, and it was my day hike pack, but the only one I had lying around when my overnight pack broke. I was shocked it would all fit in. It gouged permanent dents on my hips, so I could never put it on again, and had to give it away to the charity store. That pack was actually more robust than ED's. With the same amount of weight, ED's would have sagged more. But it's clear from photos it doesn't.
