I am currently backpacking, doing lots of hiking and camping a I am absolutely sick of carrying a backpack. I plan on sending it back with almost all of my stuff and just keeping my tent, sleeping bag and mat. I was wondering, what is the best way that I could pack this items in a way that is light and comfortable?

I am envisioning something like pic related but much smaller with good strap but I'm not sure how the best way to do it wood be. Please offer your suggestions/out/
