The question remains, and I perceive it as a more general question, how many layers of redundancy are enough, when does it become too much, and where is the balance? Additionally, what do you carry that is redundant, how much, and why? This way I can see from the voices of experience if I am on the right track or if I need to reevaluate. Please feel free to share what you carry, how much, and why.


That depends on the level of paranoia, the weather and how much you can carry, i.e. physical fitness. Choosing the right kit geared to successfully fulfill the mission and not the level of redundancy is probably more important unless of course you are purchasing junk that hasn't been tested for the appropriate conditions you will likely come across. Even Antarctic explorers such as Sir Ranulph Twisleton-Wykeham-Fienness have admitted to making this error of judgment when he admitted ditching a down jacket to save weight, which nearly cost him his life.
