Here is a peek into Ultra OCD. This has taken many years to work out but I'm 40% sure it's exactly what I need it to be.
Here's my non-drive side bags that no one sees because of strict Instagram rules.
Front NDS bag. Spare food and cook system. Each put in it's own stuff sac before going into the Anything Bag.
Rear NDS bag, which is a Specialized Burra Bag FYI. Various face and hand things. Nosehat. Neck gaitor. Etc...
DS bag that everyone sees. Shell and layer storage.
And the Yeti Rambler mounted behind it in a Specialized Burra Cage, obviously.
