Note the preparedness rule   ‘3=2=1’  … if you have 3 ways to light the stove and one doesn’t work, you still have 2 and if another method doesn’t work you still have 1 eg. matches, lighter, ferro rod.

The same applies to say light – torch, head torch, keyring torch – all could fail due to battery life.

You don’t need to apply this rule to things that rarely fail or could be repaired in the field eg. footwear – but packing some duct tape and some cordage could save the day if your boot starts to fall apart and they have many other uses too.

 

Conclusion:  Overall you are looking to be self-sufficient and will probably need to modify what you take on a wild camp depending on the time of year and the location eg. warmer sleeping bag in winter months or at high altitude. You should also have knowledge of how to deal with not having toilet facilities when you wild camp ;)
