Reading the various threads about waterproofs got me just now to be thinking the whys and the wherefores with regard to "bushcraft" not to be confused with hiking. Today I was working in my little woodland clearing brambles wearing a pair of polycotton trousers and a T shirt. I got caught in a thunderstorm and was thoroughly soaked through, but did I stop or shelter? no I wanted to get the work done so I kept on till I got home and was able to change and towel off. Did it kill me? Obviously not.
