I have several Swiss and German woolens.One pair of swiss surplus pants and shirt that is very heavy.I dyed them dark brown with black blotches on them.After shotgun season I finish off with the bow during when the weather gets cold.You cant beat them for stalking.
I like to put a pair of silk long johns and socks under them to pull the moisture off of me.( I know they look like something your Wife or girlfriend would put on but there made for men),you can find them in Gander Mountain.They are worth every cent you pay for them.
After a long days walk when the temperature drops down below zero, for me that hapens a lot of times,and when you get your camp set up take them off and hang them up for a few minutes,wollen and all and brush the ice crystals off and lay them out in your sleeping bag so you can put them on in the morning again nice and dry.
Even if you get caught out in the open,take them off,I know its cold but it wont take long for the sweat to freeze into crystals and brush them off,and put them back on if that is all you got.It will save your life.With wool you can do that.It is a lot faster then trying to dry them by a fire.
been there >dun that. Lp.
