I Guess I am not as worried as some people about cotton clothes. I know that there are better clothes to wear than jeans but I have been unable to find another pair of wool pants and I'm either not happy with the other manmade fabrics or unwilling to pays some of the prices of others. I'm 44 and I have been in the field more in jeans and BDUs than dressed any other way. I have dropped thru ice into creeks with jeans on and lived to tell about it. When hunting I have spent (unplanned) nights sleeping out on several occasions dressed in jeans and polypro. As long as a little common sense is applied with some survival knowledge and a person knows how to use the gear in his/her bag there a good time should be had by all regardless of what your wearing.
