Sometimes I think people have too much time and too much money to waste. I use cheap slip on fleece pants. I buy them at the farm store for around $10. They are warm, comfortable and dry easily if they get wet. They weigh very little and pack small. 3 pairs would cover any hunt. I often save one pair to wear in my sleeping bag. Maybe take one heavier pant in case of extreme cold. Have fun and post pictures of your moose.
