My bag is my old green school laptop backpack. I have a UST tube tent yeah it’s shiny but with 3 mylar blankets and body heat pads the thing turns into a walk in oven. One thing I noticed you and many others don’t put down is the nice inexpensive baofeng uv-5r portable radio which runs around $30 and in emergencies you don’t need a liscense for. All the others I have to modify once I get a CCW. Thanks for the great jump off points to better items to cut 75% of the weight down.
