Here is my idea: If I get a smaller backpack and strap things on the sides, I would be able to carry the same things, but it would be lighter.

So, my backpack will look like this. Sorry for the paint quality.

Is it stupid? What can I place on the left side? If I strap the pad under the bag and the tent in the place of the pad, what can I place on both sides?

Before you jump on it: I don't walk a lot in forest and I intend to fold the tent in a way tat will make the soil appear, so it won't be fucked easily.
