Good morning fellow hikers =)
I like to keep my pack preloaded with everything including trail clothing ready to go. I have a bunch of open space at the bottom so I can use a sea to summit 20 litre waterproof stuff sack basically fully extended along the bottom without any real compression. I have a marmot helium and while I do have to push the bag down to get it into the stuff sack, its not compressed like a compression sack. Can I store it like this?
How much breathing room does down really need?
