Making sure my Hammock, Insulation kit, and clothes that need to remain dry are the only things going into the inside of my pack did the trick for me.

I also went with an outside food canister instead of having to cram my food on top of everything else inside. The rest pretty much goes into outside mesh pockets where it can be accessed w/o opening up the main pack body until I can at least get a tarp up.

Suspension, tarp, wind shirt, rain pants, water filter, anything I need to get to fast, and doesn't need to stay too dry goes on the outside. Right now I can get the above inside or somewhere outside with a 14L pack.
