That is a pretty decent set of kit, although I would echo the thoughts about a 72hr kit v indefinite wilderness survival

For me, the addition of a knife and a cook pot (if it's a 5x7in stuffsack, you could house some of the kit in a tin that would hold a pint) would be necessary - then I'd add food and some extra FAK bits and I'd be good to go

As ever, the balance is between the optimum kit for the situation and making sure you have some thing with you - should I end up lost in the woods, I'd be damn grateful to have this lot with me.
