Using this as a bug out bag for my car, just big enough for a solid two days worth of supplies and clothes.
I had made a car emergency bag for my mom, and this works perfectly.
Especially for California people. But not limited to earthquakes. Good to have for any disaster. Even store in garage. Grab and go.
Enough space for everything and also squishes down enough to put under the seat on a plane.
I am a truck driver, and I always try to have a backpack ready to go in my truck in case I get stuck.
This is my new "get home bag". Stays in my truck and is more than enough bag for 2-3 day’s worth of supplies.
I'm a nurse and an instructor, and I can easily carry my course texts, a 15" laptop, and tons of other stuff with ease.
