When I teach wilderness survival I always start by asking students (and discussing with them) what some early woodsmen carried. I use the pioneers and Indigenous Peoples as examples. Native peoples generally carried a cutting tool, means for fire, tinder, supplemental food and weapons. Clothing appropriate to the climate and weather expectations. Pretty simple, right? But they had extensive KNOWLEDGE!! Trained from childhood. In other words knowledge can reduce the load!

Pioneers: carried firearms and ammunition, firemaking equipment, tinder, supplemental food, a cloth tarp, fixed blade knife and ax. A saw was a luxury item. They conquered the NA continent without much else. The steel tools were the biggest improvement over the Native equipment. Note: these were the first items that Natives tried to acquire from Europeans! Smart! Note also that in both cases hunting tools substituted for more food. Today - not the case.

So, there's my input to solving your problem - think like a Native or a pioneer - add what you can from the thousand modern choices - then gain knowledge - then reduce the load!

Cheers!
