Ok, great info here.
-I will use my headnet as a stuff sack for my coat. Perfect. I love this forum.
-I use Aloksaks for things like lighters, charging cables, and first aid supplies. These small items should be relatively waterproof in there. However, I want a small stuff sack for all the Aloksaks to prevent them from scraping on an errant buckle and ripping.
Now, I am carrying an expensive DSLR. However, I am not doing any stream crossings. So, the Ziplok Bag inside a camera case inside a hydration pack will probably do.
Relevant to this "Probably" is that I am using Ortlieb back Rollers, which are practically dry sacks. Camera can always go in there.
But, would you trust this system? Or buy one more dry sack?
So, here's the final setup:
Sleeping bag Sack (Mesh)
Food Sack (Keeping these separate because I want to keep food in it all the time for organization).
Headnet for insulated jacket
1 super lightweight silnylon drybag for first aid/repair/cables
1 super lightweight silnylon drybag for Thermarest (forgot to mention this one)
1 ultra-sil drybag (whichever is the heavier Sea to Summit) for pot, water filter, and lid
